Alternator shutting off

Alternator shutting off.
The belt had come loose and I adjusted and tightened it. Now its not working.

After I start the diesel, the alternator runs fine for about 15 seconds and then current goes to zero.

I stop the engine and restart and it does the same, shuts off in about 15 seconds.

Any thoughts?

Re: Alternator shutting off

Diode pack is what I would look at first. Is a new pack available for your Alt?

Thanks for the reply.


Probably not. Its a Valleo 24v


my experience with diodes is they work or they don't. Strange that it would repeatedly work then shut off.

Iffy connection on the pack / alt circuit breaking down under load is my suspicion.
