Machine sat and had multiple rodent chews thru out the wiring that we fixed. Also replaced the Following: ECU, Coil and Plug Wire, small Control Box that contains fuses and relays. Pick Up coil test at 219 ohms which is typically good on most machines but i can't find the specific manual on this thing to get the spec. Battery good, cranks fine but the fuel pump doesn't prime or run and no spark. Tested pump with direct 12volts and it works. If we supply a ground to the pump it primes and works but still no spark. We have traced all wiring including grounding and all is good. Tested key switch. I has (4) positions. 1 - off, 2 - does nothing, 3 - powers up everything (lighting and odometer and powers ECU, 4 - starts engine. The key switch only has 3 wires. 12v in from battery and 2 - 12v out which is power to the system and send 12v to starter relay coil.
Are these electrical systems actually switching the grounds on and off vs the traditional switching the 12v+ on and off.
at my wits end with this thing.
Also when we figure this problem out we will post the solution. seems 90% of people that ask for help on these forums, never post the fix which make this pointless.

Bike was flooded in tropical storm. Replaced ecu and coil. Motor turns over but no spark have 12volts on one wire of coil. How much voltage should be on other small wire? Crank position sensor is about 200ohms. . Cleaned plug with sandpaper. Want a wiring diagram to check voltage at ecu. I have update. The blue wire going to coil has no voltage when turning it over. The white with black stripe has 12vdc when key is turned to on position.also, how do I clean the connectors on ecu? I dont see how I can get a screwdriver in there to release them. Found a schematic.i still need to clean connectors though
Last October we were sitting at an idle on a Sunday morning and it died for the first time since we time since we bought it new I've already sent it to the shop because it's under warranty after trying to fix it. New fuel injector new spark plug couldn't do a compression check because I couldn't find anything to fit it but now that it's at the shop I have a feeling that the exhaust valves tighten themselves up and they are not closing anybody ever have this problem?
Purchased it used a week ago. Found that it wont start from key but will start if solenoid jumped. Also noticed that brake lights don't work checked switch and its working, may be the no start problem from key.
Turn signals and hazards do not work headlights tail lights and hi beams all work.
have a manual but it is hard to decipher.
Hoping that someone has run into these issues and can point me in the right direction with the lights. I believe if i can get brake lights to work it may solve starting from key issue.
I had mentioned in a previous post that I had removed the front anti-roll bar from my 2020 Outfitter 400; I ran that way for a month or so without noticing any downside however recently I installed a 'suicide knob" (see below) to assist my Parkinson's disease affected arms in turning the beast--but after doing so i found that in the quicker, tighter turns the knob permitted the vehicle would nosedive a bit, dig in, and plow on hard surfaces--not scary, but quite noticeably.
So I put the bar back on. Then today I got about 1-1/2 miles down the main road on the nearby power lines, turned around and came home to take it off--with the bar on, at 25 to 30 MPH, the front-end of the beast jumped like rabbit at each bump in either wheel rut., for a nearly brutal and quite uncomfortable ride. the bar (20 mm solid steel) is far too robust for the weight of the vehicle. The front bar on my 3900 lb. Infinity M37 is 30 mm...
suicide knob--for you younger folks:

my name is albert i have in my shop a hs700utv that im getting no fire to coil i replaced the cdi and checked the relays and ignition switch out getting power to the cdi but nothing to coil and i didn't find any broken wires. they said that it was running fine and then it just stopped and wasn't getting any power to the coil is their another sensor on here that will stop it from firing i have looked at a wiring diagram but im not seeing anything different from what i know i checked the cdi and im getting fire to it but not to coil and this is a second coil no difference and also this is a delphi cdi 2 port is their any way to check it i know im getting power to the black plug in cdi on the # 10 the green and black wire but nothing else the blue and black wire is opposite of it the emergency brake and neutral switch is working is their a obd II plug for this i found one in back of pickup bed but i cant find a scanner but im not sure if it is one and im getting power to the stator the threee wires im at a lost here

We bought a Hisun 700 UTV, used. It has an issue when you run it in high. It drives but acts like it is shifting when you get around 35mph. Clutch looks good. Read many articles and not sure transmission or something in rear of UTV. Looking for any advice.

We just got a used Hisun utv which burns oil like crazy and needs a diff seal. I'm having a hard time finding parts so far so I was wondering whether two models were the same. Our model is Supermach 700U 2008. Many times the Hisun HS700 shows up when looking for parts. So are the parts between these two models the same? Are the essentially same with different stickers on it?

2009 Hisun 700.... previous owner did a number of changes. This part is under the driver's seat but not attached to anything.
Is this the old fuel pump?
