  1. Are you talking about an electric heater? if yes its likely too much current. There might be 10 amps of available current coming out of the rectifier that isn't already claimed by the ECU and factory lights. 10 amps @ 12V = 120 Watts, which is about what an electric heating pad runs. If you're talking about a fan for a engine coolant based heater it's probably ok. If you have accessories and the running voltage is below 13.5V you have too much stuff attached. If the battery light comes on it means the battery is actively being discharged while running. Stator based charging systems on these things and tractors etc are really meant to power the ECU and factory systems not to provide a lot of extra power for other stuff, it's not like the alternator on a car.

  2. Since I've seen some questions on this I took some pictures and will provide instructions on a valve adjustment for the UT400. This should be the same for the 550's and other various Coleman/Hisun single cylinder models with the cylinder slanted aft. I have seen several people ask of it is really necessary, and read several reports of valves being out of adjustment from the factory. My valves were .004" intake, and .010" exhaust with about 5 hrs on the machine. I've seen different numbers thrown around for factory spec, but I decided to go with 0.005". This is called valve lash. What is is is a gap between the rocker arm and the valve then the camshaft isnt opening the valve. Why does it matter? If it's too large the valve doesn't open all the way, if it's too small the valve dosent close. This can cause valve damage (overheating) as well as loss of engine power (burned fuel is going out exhaust rather than pushing the piston dow). Tools required : 5MM Allen wrench, 10MM box wrench, needle nose pliers, flat feeler gauge set, rags First you need to remove the fan cover on the passenger side. There is a cooling vent hose on the back side, remove the hose clamp and slide it off. From there there are 4x 10mm bolts holding the cover. The forward ones can be accessed from under the seat. Next remove the spark plug from the drivers side. Carefully wiggle the spark plug wire off. Grip it as low as possible and give it a little twisting motion as you pull it off to help free it. Its a tight fit for a socket, but there is a sheet metal wrench in the toolkit that fits it. Unscrew the plug and set it aside. This allows you to spin the motor over freely with no compression to fight. When you reassemble this is a good opportunity to switch to an NGK iridium plug for better performance/less fouling DR8EIX) Next you need to remove the intake and exhaust valve covers. The intake us the forward one. There are 3x 5MM Allen screws to remove. The Exhaust is the rear with 2x 5MM Allen bolts. Both covers have O-Rings instead of gaskets and are reusable. When you remove the rear be careful and use your rags as there will be oil that drips out. Next up we need to spin the motor over to top dead center. Grab each rocker arm and give em a little wiggle up and down. Spin the engine over by grabbing the fan with your other hand. Spin the engine over until both rockers have some wiggle and are loose. Once both rockers are loose slide the feeler gauge in like shown above. Try different feelers as needed to determine your starting spec. You should feel some drag but still be able to move the feeler without too much force. If you need to adjust, use the 10MM wrench to slightly loosen the locknut, then with the correct feeler gauge in place, tighten the top square nut while wiggling the feeler in and out. Once you have it right you need to tighten the 10mm lock nut without moving the square head bolt. Once the lock nut is tight recheck the clearance. That's it, button everything back up and make sure you have it all reassembled before running it again. If you find this helpful give me a thumbs up or comment. If you have any questions or need more help let me know. If there's interest maybe I'll do some more of these

  4. I just got off the phone with the company that makes the TINY SCAN 301 and the TINY SCAN TS-140 the TS-140 is the one I have he told me both come with a plug on them that will plug into the Hisun UTV although I have heard the newer HISUN's use OBD2 if you have a UTV like my 2018 HISUN HS-550 Performance made for Rural King by HISUN Motor Company in Texas either Tiny Scan TS-140 or 301 will plug directly into the Hisun diagnostic plug which I finally found when I took the bench seat out and opened the lid over the engine compartment and looked down the driver side of the Engine and found the wire laying way down beside the engine lifted it and low and behold there was the 6 pin diagnostic plug with a plug-in cap that has to be removed to plug in the scanner and replaced to keep dirt and stuff when finished. Hope this helps someone. Oh the 301 does a lot more like connect to iPhone, Android, or PC via WIFI with it's own IP address but is a little over $300 the TS-140 reads and clears codes and only costs $169.

  7. I have a 3500LB Winch that only runs in one direction. Inward but not Out. Replaced the solenoid module. Makes "click" when I push the "Out" button and the motor tries to spool out but then stops and begins to "click". Does anyone have suggestions what I should try next?

  8. 2 switches installed. The remote (tethered) and the dashboard toggle switches react both the same way. Push "Out" and the motor attempts to start but stops and then it "clicks" .

  9. We see a lot of the UT400 with shift problems, not going into gear, popping out of gear, grinding etc. There is a bulletin Im sure everyone has saw about adjusting shift cable. That dont always fix it. I went round n round with coleman on couple units. We are a Coleman warranty repair center"AFS Small Engine Repair " I told them shift lever does not have enough travel . No amount of cable adjustment will increase travel . I extended lever with piece on flat iron by 3/4 of inch . This gave shifter enough travel to properly engage into gear completely . Last couple units to come in for this Coleman sent me a modified shift lever, with longer travel . Problem solved! Also , heads up if you get any new unit ,,,go over and check it out, grease all zerks, check air filter for being in backwards, check wiring harnesses for rubbing on rotating parts, brake hose routing , make sure not touching exhaust . These are just few of the more common failures I see .

  10. You just need the VAG-KKL and the 6 pin adapter. Those I can confirm work, other ODB-II solutions may or may not work I have not tried them.

  12. Hey Folks There are not a lot of good sources out there for troubleshooting and diagnosing ECU problems with the Massimo Buck, Bennche Bighorn, Bennche Cowboy, & Cazador machines that use the Delphi MT05 ECU. They are all basically the same with different badging, so I thought I'd share some info that I found during some searches. I was trying to help someone diagnose and repair a hard starting issue. The ignition coil was throwing a 0351 code. I discovered how to read codes without an OBDII code reader. The following procedures should help you check your fault codes and clear them if needed. Fault Code Troubleshooting for Delphi MT05 ECU on the Massimo Buck 400, Bennche Bighorn 400, Bennche Cowboy 400, and Cazador 400 *NOTE: The MT05 ECU is not really OBD 2 compliant. It is much more similar to an OBDI system. The MT05 ECU controls either 1 or 2 cylinder engines commonly found on Massimo, Bennche, and Cazador. Much of the ECU info was found here: https://netcult.ch/elmue/HUD ECU Hacker/Delphi MT05 Manual.pdf Delphi EFI System Design Delphi EFI employs 5 sensors to monitor engine performance. 1. Crankshaft Position Sensor 2. Coolant Temperature Sensor 3. Oxygen Sensor 4. Throttle Position Sensor 5. Manifold Air Pressure/Manifold Air Temperature (MAP/MAT) Sensor Delphi EFI employs the following system components. 1. MT05 Engine Control Unit (ECU) 2. Fuel Pump 3. Multec 3.5 Fuel Injector 4. Idle Speed Control Valve (Idle Stepper Motor) 5. Multec Ignition Coil 6. Fuel Vapor Canister Purge Valve Using the Digital Dashboard to Decipher EFI Trouble Codes In addition to commercially available diagnostic scan tools (Big $$$), you can use the engine warning light of the Siemens dashboard to diagnose most of your EFI problems. The digital dashboard receives signals from the MT05 ECU, and the engine warning light will flash a diagnostic trouble code (DTC) if the ignition key is switched on/off for three cycles. When you turn on the ignition, the engine warning light will illuminate, which indicates the EFI system is operational. After the engine is started, the engine warning light will extinguish if the EFI system is working properly. However, if the engine warning light remains illuminated, it indicates the EFI system is not working properly, and there is a system component failure. Deciphering Diagnostic Trouble Codes To read the diagnostic trouble code (DTC), open and close the ignition key three times in rapid succession, as follows: open/close—open/close—open. At this point the engine warning light will flash a DTC which indicates the fault in the EFI system. Refer to the attached fault code table to identify the corresponding problem. The engine warning light will emit a sequence of flashing lights. If the light flashes 10 times, the translated number is 0. If the light flashes one time, the translated number is 1, et cetera. For example, if the MAP/MAT sensor is disconnected, or the connector is shorted to ground, the engine warning light will flash in the following manner (This is an example only). The engine warning light will flash 10 times: The first number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 1 time: The second number of the DTC is 1 After an interval of 1.2 seconds, the engine warning light will flash 10 times: The third number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 7 times: The fourth number of the DTC is 7 The resulting DTC is P0107. NOTE: For the system I was helping to troubleshoot, I suspected an ignition coil failure due to the code that was thrown. When it was checked, it was flashing: 10, 3, 5, 1. The 10 represents a 0. So the actual code was 0351. After finding the code, the coil wire was checked and discovered loose at the spark plug. Once it was pushed fully on, the problem was fixed. Most likely, this problem was created after the owner had pulled the spark plug to check the gap. The ECU was rebooted using the procedures detailed below with no more codes being thrown. If there are other fault codes, the engine warning light will flash the next code in 3.2 seconds after finishing the first sequence. After all existing fault codes are flashed, the engine warning light will repeat the fault codes in a loop sequence, until the ignition key is turned off. To clear fault codes you either need an OBDII Fault Code reader and a Delphi 6 pin connector adapter cable that you have to order from China and wait 8 weeks…OR....you can simply reboot the ECU using the instructions detailed below. Rebooting the ECU Perform the following steps to reboot the ECU. 1. Turn off the ignition for 15 seconds. 2. Turn the ignition on/off for 5 cycles. Make sure each cycle lasts about ½ second, verifying the start of the fuel pump for each cycle. If the fuel pump doesn't start during any cycle, begin the entire reboot procedure from the beginning. 3. Turn off the ignition for 15 seconds. TPS (throttle position sensor) re-learn procedure after rebooting ECU. This should be done after replacing the TPS or the ECU....and it is advisable to check proper idle after rebooting an ECU too. Source: ECU Hacker (Reworded process slightly to make it a more sensible flow in my mind): 1. Turn the idle screw one full turn clockwise before starting 2. Start the engine, and run at low idle until the engine warms. Maybe a couple of mins. 3. Idle should be above 1500 rpm. If it isn’t, turn it up to 1700 then shut the engine off. Do another reboot of ECU. 4. Restart the engine and let it stabilize at 1700 rpm. Then turn the idle screen down to 1500 rpm and let it stabilize for a few seconds. Once it stabilizes, set to the final recommended idle speed for your machine. The placard under (or behind) your seat should show idle speed, valve adjustment, spark gap, etc. Typically the 390 cc engines in the "400" machines run at 1600 rpm idle. 5. Shut it down. Wait 10-15 seconds before restarting. The procedure is now complete. Final Notes: I have included pictures of an OBDII connector and the Delphi 6 pin connector in case anyone wants to go buy stuff off ebay or local parts suppliers and build a connector to use for an OBDII reader. But...you can save money and simply do the same thing with code reading and resetting using the check engine light on your dash. Some folks prefer to do it with code readers. Hope the information provided helps if anyone ever needs it but cannot find it in repair manuals. I discovered most of this in some motorcycle forums. The source for the diagrams is here: https://netcult.ch/elmue/HUD ECU Hacker/ Be advised: I am not a service technician. I do not endorse any manufacturers. I do not get paid to help, nor do I want to. This is just a hobby of mine. I enjoy working on things and solving problems. If you run into a weird problem that stumps you, give me a shout. I may be able to give you some ideas...or not. Just know, that troubleshooting thru emails can be challenging. The more info you can provide, the better. Otherwise, I will probably ask you a ton of questions. The good news is, the Delphi system used on these machines is essentially an OBDI and it is very simplistic. If you are methodical and patient, most of your "problems" can be figured out thru a process of elimination. Always go for the simple things first before throwing money and sensors at a machine. Take care - JT

  13. Regular car oil doesn't have the stuff needed to keep wet clutch lubed like it needs Just make sure the oil rated "JASO MA" or "MA2". Synthetic or conventional is up to you. I read somewhere that the "MA2" rating is for engine exhaust with a cat and O2 sensor. And I think the synthetic lets the clutch slip more than conventional. If there is a lot of miles on the clutch with conventional oil. Then switched to synthetic. The clutch is more likely to slip.

  14. In order to connect with the ECU we need two cables. The first is a USB ODBII cable. HUD ECU Hacker’s documentation has a lot of different confusing options, but here’s what I went with and managed to get working, the cable is called “VAG KKL” it is a USB to ODB2 cable. It is available from a variety of sources for $10-15. The second thing we need is a “6 pin delphi to ODB2” adapter cable. It is also available for a similar price. In my case I ordered both from ebay, but there are other sources. Once we have our cable in hand we need to find the plug it in on your machine. My personal rig is a Coleman UT400, but the wire location should be similar for all Hisuns. My cable was located under the middle of the seat area. Just inboard of the battery, where the main wire harness split loom runs. The cable is a 6 pin (3x2) with a dust cap. Remove the dust cap and plug in the 6-pin end of the Delphi adapter cable. Note: When I was done, I left the 6-pin adapter connected, and zip tied it so it now runs to in front of the battery for easier access in the future. Next download and install HUD ECU HACKER DOWNLOAD Open HUD ECU Hacker on your PC It should prompt you to choose a driver to install. This particular cable uses the “CH340” driver (First choice on the menu) click to install, once installed hit the X in the corner to go back to the main page Once the driver is installed plug in the USB Cable, and plug the ODB2 end into the 6 pin adapter. The red led on the adapter should light up indicating it has power. Drop down and pick a com port on the main screen, it should show the VAG KKL adapter as a com port. Click connect on the main menu. It will pop up a bunch of fast scrolling text indicating it is connecting. Once connected you can click through the various tabs to see different data sets. The main menu also has the option to show fault codes, clear fault codes, reset the EPROM back to factory. The other function that may be helpful is recording a log file. You can record a log while operating the unit, and come back later and replay it to try to better diagnose what is happening. Within the various pages you will see the reading from each sensor. Sometimes a sensor reading will be off enough to cause running issues, but not enough for the ECU to realize its an issue. For example if the engine thinks it’s really warm, but its actually cold, it may not inject enough fuel to start. There are also more advanced functions, like adjusting fuel mapping, but that is beyond the scope of this tutorial. Full HUD ECU Hacker Documentation (Very technical reading) If you find this helpful give me a comment below or a thumbs up.
