I just got another fourtrax 300 4×4 and have an electrical problem. The atv came without a battery and the kick start does not work. I went to install a new battery, I attached the positive terminal, but as soon as I touched the ground terminal the starter would start cranking. So I think the solenoid is sticking and replace it with a brand new one, but same problem. With the new solenoid as soon as I touch the negative terminal with the black wire the starter starts cranking. It will do this even with the key not in the ignition. What do you think is causing this issue?
