Fuse Blows When Trying to Start Engine
OK, I've read the Yanmar starting problem threads, but this is different enough to a non-electrician like me to warrant the question:
Yanmar 2GM20F has always started fine--switch on, alarm sounds, one press of the button and it starts. Yesterday, though, when trying to start the engine to bring the boat back in, we got: switch on, alarm sounds, press button, no starter sound and the alarm dies. Then nothing. I found a blown 30-amp fuse in a wire to the starter. Replacement of the fuse, along with cleaning off a little corrosion in the fuse holder, got the power back only until I hit the start button again, which blew the fuse again.
Am I looking at the usual wire issues? Or could it be the solenoid? The connections at the starter look good and clean. Ditto with the connection up at the switch.
Thanks for your help!
