Hello,
I recently purchased a 2002 yamaha 4 stroke model T50TRA. I was next to the boat, in my yard when the motor starter began to operate with no key in the ignition. I quickly unhooked the wires at the battery going to the engine, leaving the other smaller lighting/helm control wires hooked up. Now when I hook the motor wires to the battery it starts to turn the starter. (90% of the time) I thought the problem went away but it happened when I put it on the water. I was able to operate it the day by unhooking the wire, and when I wanted to start the motor I would turn the key and touch the wire, removing it immediatley after the engine started.
Batteries: brand new.
Unhooked wires to ignition switch under helm and unhooked 2 minor harnesses under cowl to try to rule out a faulty ignition switch. With the various wires unhooked, it still tried to start when I touched the motor wires to the battery.
Any ideas?
I am thinking starter solenoid. What does the relay mounted on the engine do?
