Hi, guys i was riding my 2002 honda rancher 350 2x4 ES all weekend and it was running great. At the end of our trip we were on a small trail just riding around and my atv just lost power completely. I went to start it and the battery went dead. So i tried to pull start it and that didnt work. So i let it sit for a couple minutes and then it fired right up using the electric start which was really weird. So then it was running fine....when i got home it did the same thing..lost power and then it would only start with the pull start. I charged the battery and it seems that my battery keeps getting drained out. When i got it going again with the pull start it ran fine until i went to put it in my shed and then my digital display went blank but the atv was still running and i couldnt change gears the neutral light flashed on and off a little. I have no idea what is wrong with it. If you guys could help me out that would be awesome. sorry i wrote so much
Thanks, Any help is appreciated

Welcome to the forums. I would charge the battery up completely and start it up and use a voltmeter to check the voltage and see what it puts out when running.

I had a problem like that when i put mine back together. It ended up being a plug loose under the right rear fender

why would it matter if the battery was in the fourwheeler? I thought the only thing the battery was responsible was for starting. But since i have a pull start shouldnt it shift too?

The electrical system uses the battery to 'smooth out' the power. If the battery wasn't there, the whole electrical system, including the ES, would act very flakey due to the condition of the power.

Yes, it could have problems shifting.

Even if the battery is in the ATV, if the battery drops below a certain voltage, the ES system won't function correctly. So the battery needs to be in and fully charged.

If the battery was below that certain amount of voltage would it cuz the atv to temporarily stop running occasionally for 5min or so?

I doubt if it would cause that, or at least I don't think it would. If it's doing that, it sounds like something's getting hot and causing it to quit. I would put a good battery in it and try it first, though, just in case.

you need to make sure the voltage is a min. of 14.5 when the engine is running , if not the rectifier is probably the problem this can also cause the unit to quit , due to a lack of voltage if your electric shift continues to give trouble , you can order a bolt on hand or foot shifter for your es at docsatvservice.com

go to docsatvservice(dot)com and he has a bolt on hand or foot shifter for the ES models. i have this on my foreman 450 and when i get into the woods it gets me out. And on docsatvservice(dot)com he has a module that bypasses the ES wirings and is direct. i put that on my foreman and now i can go through mud and it will work and the ES has not given anymore problems since. his number is 601-659-9931
