I have a 1990 Bayou 220 that runs pretty well for it's age--needs a new muffler, but sounds tough. Have had to start with a pull cord since I got it, and recently started troubleshooting the start button. Finding a lot of information on this issue in the forum, but haven't been able to chase it down yet. Got a new battery, new starter solenoid, and going to replace the starter relay this week, but not convinced that's going to do the trick, since I can't get the neutral light on when turning the key on. I can start it by jumping the solenoid, but the 2 black wires to the relay do not activate the starter. Bad ground or a short somewhere? Is there a good way to just test the ground?
