Hello All,
Was out boating this weekend and had the battery die on me in the middle of the lake. Just clicking noise, not even cranking...
When I got back home, I measured the voltage on the battery with no load -- it was 12.2V.
Charged it up (12.7V) and plugged it back in. Was able to start on ear muffs. Measured the voltage with engine at ~ 1500-2000 RPM -- was 12.5V at battery terminals and at alternator output. With blower and lights on -- was 12.3V at both locations.
Took the alternator to advanceauto and autozone -- none of them were able to connect it. Said they need to know the automotive p/n so they can come up with the right connector.
So, does it sound like a dead alternator or something else may be wrong?
It's Mando 55Amp p/n 155603 alternator. Engine is Mercruiser IO 3.0L Alpha One p/n 0L013754
One more thing though. About a month ago we took the boat on the lake after it's been sitting for over a year. Few minutes after we were cruising, I smelled burnt wiring, stopped the engine and opened the motor cover. There was some smoke coming out of the alternator. Waited a minute and restarted OK with no smoke or smell. Since then, we've been at the lake at least 5 more times. Thought maybe something got into alternator and burnt out...
Any suggestions are greatly appreciated.
