Alternator is hot with engine off

[skunkman]

Last week I posted an issue with my port engine not starting. I checked the batteries and they seem OK. Today I went to inspect the engine and I found that the alternator was very warm to the touch. Hasn't been run in weeks. Engine will not start even in emergency mode and the scanner gives me a "port engine not communicating" warning. Any thoughts?

Thanks

Sounds like a failed alternator... diode pack maybe. Drained your batteries down... disconnect it!

That was my thought - I did disconnect it. Hopefully Marine Max has an alternator and I can get up and running

Would a bad alternator prevent starting even with voltage directed from my starboard engine?

I think the alternator diodes are shot and the starter fuse is blown I replaced the alternator but I am Having trouble getting access to the starter fuse. What engineer would put a fuse that is essentially unreachable???

I've often done that .... right after the sales guy calls from the 14th tee to ask if the project is gonna finish on time!

One pint of blood later I removed the fuse. The engine started right up. When I started the starboard engine the port engine died and would not restart. Bypassed the fuse (I know, bad idea) and still n start. Time for the mechanic!!!
