Hey there! New to the ATV world and forum. So lets get this started with a little backstory of my situation.
Recently I bought a 2008 sportsman 500 HO EFI for a good price, knowing it needed some work. I like to tinker so I figured why not. Literally knowing nothing about ATVs I decided to challenge myself and go through with the purchase.
Known issues:
MPH didn’t work.
4WD didn’t work.
RPM didn’t work.
Rear boots torn.
Battery light kept flashing.
Along with a few other minor cosmetic things.
What I have done so far:
Replaced the speed sensor, (unrelated to this issue), but fixed the MPH.
4WD works now, but very clunky, I bought an aluminum roller cage and rollers, (not installed yet, not a priority).
Bought a Caltric stator/pulse coil combo and voltage regulator and installed.
Fixed both rear boots, new axles on order though.
Bought a new belt, the one installed looks freaking perfect though, its a good backup.
So now we go into the problem at hand. Most of the stuff I have done has gone smooth, I just take my time and google the crap out of stuff. So in order of the installs I have done.
CV boots. These were actually the most pain due to trying to band them while on the ATV.
Speed sensor.
Adjusted the thumb throttle due to excess play. It never caused a cutout though.
Stator and pulse coil. Was running perfect except for the flashing battery icon.
Voltage regulator. Seemed to fix the battery icon. Still running.
Now this is where I am confused. It seemed that when I went to change the belt things stopped working. It’s a simple process of removing the old belt and putting the new one on. I have read that sometimes with aftermarket belts, it can bind one or both clutches and stall it. Both clutches move freely with the new and old belt installed.
Troubleshooting I have done, all while screaming :wtf1:
Threw the old belt on, same result.
Plugged in the old voltage regulator, same result.
Threw the old stator and pulse coil back on, same result.
Checked the thumb throttle for cutout, same result.
When I go to start it, it almost sounds like it’s not getting gas. I give it throttle and it will rev up, sometimes sputtering, but it will stay running. To me this can rule out a fuel pump and the associated relays/fuses. When I let off of the throttle, it shuts down immediately. Then when I go to restart it it does 1 of 2 things. 1, it takes a second for it to turn back over and I can repeat the process, or 2, I turn the key and get nothing, no cranking no starting. I hear the audible sounds of the fuel pump turning on to prime the system and the audible clicks when i turn the key fully off.
Could this be as simple as an ignition switch? The last thing I remember messing with was the ignition switch to try and straighten it out, but this was just moving and tightening the plastic nut that holds it to the light pod.
Or do you think I should try to look at something else?
Sorry for the long post but I was to give as much info as possible. Any and all help would be greatly appreciated.
