Hi guys first time post here. I have had many dirt bikes and quads currently riding a Brute Force 650 and I bought a 2011 Sportsman 500 carb from my neighbor to leave where I hunt, he used to it to plow a bunch of driveways last year and then parked it outside a month later had a dead battery and couldn't start it, he charged the battery and even tried a new one. None of the lights etc. come on. I bought it for $1,500 with the plow.

I am trying to figure out what's going on. The battery is charged and I have power in and out of the circuit breaker under the seat, and at the fuse block in the front. I have checked for power at the rectifier and have power in and out, I have checked power at the switch and have power as well. I am able to jump the starter solenoid and the motor turns over, but no spark. I changed the key ignition only had 1 key and most recently the CDI box because we figured with power coming to it and but no spark maybe that was the cause. No good. I am kind of stumped here and haven't seen anything online resembling this issue. I don't want to keep replacing parts to figure it out. It's weird it seems like its dead. No head lights, no tails, no gauge lights, no clicks or noises. Anyone with some knowledge or suggestions? Trying to get it running for next weekend so a friend can come trail riding with us.

 

With no lights or anything, I would address that before putting ignition parts on. My first idea would be check the wiring and connections at the left handlebar switch. Seen lots of problems there. Will look at a wiring diagram Monday and see if I can come up with something for you.

 

 

The fusable link is after the supply voltage to the solenoid so they wont affect jumping the solenoid. Will still try to look through the wiring and see about a possible way to bypass or jump the handlebars switch.

 

Can you see if you can find the sticker that shows the VIN number and production date? In the wiring diagram there is a "built on or after"(production date) to 2 different wiring diagrams. I dont know what the difference is, but Id like to look at the correct one to try and help. I think I have it figured out. Just want to verify.

If you cant find it and can find your VIN on the frame, you could PM me that info and I'll contact my dealership buddy and have him run it for me and get the prod date that way.

Just an FYI, when the vin gets ran at a dealer, it will show the name, phone number, address, etc of the original buyer so there is some info that can be seen. Nothing that can be used in a bad way, but info none the less. If you are worried about send me the info because of that I understand. WE'll work around it if so. It might make it easier to figure it out though. Totally your call on the vin.

 

If it was me I'd PM the VIN, but I wouldn't post it on here like I've seen some people do.

 

I think you need to jumper the red/black to the red/white. The part I circled in green is just something that I find strange. I'm not positive that connection is made when in the "On" position. I don't like they drew it, but, on a lot of machines the red/white always has 12 volts when key is on so I think I'm correct.

 

 

I would find a used kill switch, or swap one out with someone else, to rule it out. I had a no power issue, and that is what my problem was.
