6.2L Merc with starter issue
First let me say that I have read the sticky thread on starter issues. But let me give you some background...
I just bought this boat a little over a month ago. We ran it 4 times in fresh water and no issues whatsoever. The last time we took it out, it started overheating as soon as we left the dock. I immediatley turned back around and shut her down. Once I got her home, I realized that the impeller had disintegrated. There was nothing left but the rubber shaft! So I replaced the impeller and the whole water pump housing. I wasn't able to test run her on land because my intake is on the bottom of the hull and I can't get a flusher under my trailer. So I took her back out to the lake to see if the impeller worked. When I turned the key, I got a very loud almost metal sounding bang, and the engine did not turn. I freaked out and thought the engine had seized up. So I took it to someone who looked at it and hit something back by the starter and the engine did bump over a little. We found that terminal A on the starter solenoid had disintegrated and the rubber boot over it was melted. I replaced the connector and tried to bump the engine and get nothing now. No click or anything.
So this is what I get following the sticky starter thread: I get voltage on Terminal A of the slave solenoid with the ignition switch off. As soon as I put the key in Accessory position, the voltage disappeared. I got no voltage on A, B, C, or D of the slave solenoid. UUUGGGGGHHHHH
I have tried to remove the ground wires on the grounding buss bar to clean them but they are frozen on there! So I am soaking them overnight in JB Blaster and will try tomorrow to remove and clean them. I am just hoping that after all this that my engine will actually crank and isn't toast!!!
Anyways, any help would be greatly appreciated....
