Alternator questions
« on: August 02, 2006, 11:35:53 AM »
I noticed over  the weekend that my alternator was running extremely hot - so hot that it was still very warm 12 hours later (with the battery disconnected the whole time) - quite a bit warmer than the engine.  I took it to Advance Auto - they checked it out and said it was working fine - so I have 2 questions.

How hot should an alternator get?  I've never really paid too much attention to it before.

If I do decide to replace it or get it rebuilt, does anyone have any suggestions.  None of the normal suppliers (Performance, Year One, etc. seem to have an exact replacement - and I kind of wanted to stick with a Delco product.

Thanks.

A local rebuilder should be able to rebuild your alternator.-Alan

You have to remember that thing is a heat sink because its connected to the engine block. Its not unusual for them to stay warm a while after shut down. Especially since the nights here lately only get DOWN to 83 :shock: .
