Twice my hisun has been driven a few miles and turned off back at home. Get back on it same afternoon and console is dead, no lights.Â
Have 12.7 vdc at battery and fuses are good. I hear relays click in the fuse box and main relay clicks but everything is dead.Â
Any ideas on what this may be? I've seen this problem before on this forum but it never finished.Â
Any help is always appreciated. Thanks in advance!Â

This post will explain how to hook up your PC to the ECU of a Hisun/Coleman/Etc UTV to be able to read error codes & engine parameters for troubleshooting purposes.
This is applicable to all small engines using the Delphi MT-05 ECU. This should cover all fuel injected Hisun models, as well as various other Chinese FI engines, as the Delphi MT-05 ECU seems to be the favored ECU solution.
Even though we get actual engine error codes to display on the dash, sometimes we have âpending codesâ (not yet confirmed by the ECU) or other intermittent issues that are hard to diagnose, for example a poorly connected sensor that may give intermittent false readings, or a sensor thatâs putting out bad date, but not bad enough for the ECU to realize.
The setup requires 2 cables, which are available for around $25 combined, a PC with a USB port, and some charityware software called âHUD ECU Hackerâ. This gives the same functionality as the $300 dealer code scanner for a fraction of the price.
In searching I found info about HUD ECU Hacker, but I have yet to see info anywhere about how to hook it up to a Hisun, so I took the leap and bought some cables, and made it work. I will show a step by step of how to do so in post two.
I will be breaking this down into 2 posts:
Delphi ECU Info & Overview (This post) System setup & use Delphi ECU Info (Skip ahead to the next post if your eyes glaze over technical details)
The Delphi MT-05 ECU was developed to allow small engines to use fuel injection. A fuel injection system requires feedback from various sensors to operate efficiently. This feedback allows the adjustment of ignition timing, fuel injection volume, etc to efficiently and cleanly produce the most power possible from a given engine.
The MT-05 ECU has a number of sensors that are required for proper functioning including; Coolant temp, crankshaft position, intake temp, intake pressure, exhaust O2, throttle position, as well as some other optional sensors that are used on more complex vehicles.
From the sensors the ECU adjusts: Fuel injector timing/pulse, Idle air control valve, and ignition coil
The Delphi MT-05 puts out diagnostic data, however it is not ODB2 like a modern car, where is where it gets tricky reading it. There are three options, there is an old 16 bit piece of software Delphi has that is not able to run on a modern computer, there is the motorscanner tool for dealers ($300), or there is freeware HUD ECU Hacker with the proper cables.

Hi All,
I picked up an old beat up 2010 American Sportworks Bull Dog 300 BD300. I would like to restore her... Does anyone know a good source for parts other than the OEM? I find $130 for brake pads is kind of unreasonable... I also need a steering rack and other things... I took apart the steering rack and it needs a new bearing and oil seal... Of course the OEM only sells the complete rack for over $200.. I found the correct bearing for $6.00. I am having trouble finding the correct oil seal..Â
Anyone that has info on one of these machines, please chime in... I am used to the ease of finding info on Polaris, Honda, Can Am, Kawasaki, etc....., Info and parts on these seems to be scarce.. Some of the parts on it look like Golf Cart parts as well as some look like Go Kart parts..

American SportWorks LM 650 wonât start at times. Starter wonât engage the solenoid just âclicksâ much like a weak battery would cause. Battery was replaced and problem went away and then came back. Replaced positive battery terminal. Problem resolved then returned. Replaced negative battery terminal. Problem gone then returned. Replaced the positive and negative battery cable ends. Problem resolved and now returned. The repair lasts for maybe 12 starts, then the solenoid just âclicksâ again as it will with a weak battery. So I replaced the ignition switch. Problem solved for a week. With each âfixâ the problem is resolved but only temporarily. Does anyone have any suggestions ? To replace the starter is expensive especially if itâs not the problem.Â

We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used.Â
The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn.Â
THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
Thank you!
