Hello! I have a 2003 Polaris Predator 90 and the electric start stopped working. It would be a hit and miss if it even turned over or not for a couple of months, then it would make a buzzing noise, then ceased to do anything at all. It kickstarts just fine. The yellow electric start button on the left handlebar switch wouldn't complete the connection when I would test it with a multimeter, so I tried shorting the two wires out, and it doesn't do anything. The battery has 12.8 volts and the starter motor works great. The fuse under the seat is was blown, so I replaced it and it still didn't do anything when I shorted the wires. Is there a way to test the starting relay? Any other ideas on what it could be? Thanks in advance!

 

Update: The brake switch was bad on the rear brake. I pulled it out and soldered the wires together and tried shorting the electric start wires again and it turned right over! Just waiting for the new handlebar switch and will be good to go!

 

You can jump around the relay to see if that's the issue.
