I had my trx300 parked today and ignition was off. I was banging on a piece of metal while I had it laying over the rear cargo bars. The 4 wheeler all of a sudden tried to start itself with the ignition key off. I noticed the spark plug cap plug and the ingition wires were apart. I could not get it to stop trying to start so I had to undo the battery cable. Everytime i touch the battery cable to the battery the starter starts turning even though the ignition key is off. It will start with the ignition key on but will just crank the starter continueously when the key is off. Any suggestions on my problem?
