Back to working on my UTV Hibred

[res2fr]

Hello All,

 I'm not really New here but Life sidetracked me for the 18 months or so but I've gone back to doing some work on my Coleman(Hisun) UTV400 SxS that has a Kodiak 400 motor/Trans and a Major wiring problem. 

Short history, with original owner there was a fire, some interior plastic damage but were told major fire damage to motor. They bought and installed the Kodiak 400 motor, CDI box and a few other necessary parts. They had someone wire it and used it then for some reason Stripped the wiring, installed a new Emark wiring harness but Never reconnected the motor wiring to the Machine. There was a mountain of loose wires, cut off connecters in the Dump Box.

I've finally gotten back to sorting and reading diagrams for both machines wiring and have the CDI box rewired in to the point I can start the motor with my Temp ignition switch, it runs ok and is charging the battery. my immediate problem with the motor right now is that it runs fine At Idle but if I try to accelerate it immediately  Dies. Im trying to figure out if it's an issue with something that the CDI box needs wired that isn't there, some switch or relay connection that's still not there Or the fact that the fuel supply being from and electric fuel pump not the original Vacuum pump that the Quad used was, I cant find the Pressure of the Vacuum pump.  Acts like there's no Spark Advance in a way but could be just getting way to much fuel, to fast. I have a valve I found that allows me to cut the pump pressure down to 1 PSI that I'm about to try and I'll keep checking the wiring diagrams looking for something electrical that might help explain this. Oh I couldn't a carb kit to rebuild with so I bought a New carb, not high end but figured it should make a difference but no such luck.

Once I get past this issue I'll go back to paying attention to getting battery power back into the new Emark Harness so I can start getting power to the rest of the machine.

Sorry all, I got a touch Wordy here. I hope to be spending more time here and Learning and if at all possible  Helping others.

Take care all and I Shall Return.

I would buy an inline spark tester and hook it up, see if you lose spark when you accelerate .

That's a good idea and I believe have a Tester,  I'll dig it out. I didn't think about that, I did put a new coil and spark plug on it but beyond getting a spark never checked for it breaking down. 

Thank you Travis, I'll post how I do.
