This past weekend I had a starting problem that I just sorted out. After getting her started and back home I noticed the alternator was very hot. How hot is normal??? :dunno: I could only put my hand on for a second before it was too much. Other components like the AC compressor were fine.

thanks

Alternators do run hot (mine does) so I would'nt worry about it too much, unless, it begins to smoke or glow red at night.

If it runs to hot you will hear the bearings starting to complian.
They will first make a grinding niose then up to a high pitched whine. If this happens you need to chek it out, then something is wrong.

Thanks! I recently picked up a Bosch 120amp alt to upgrade, but have been trying to source a pully so I could leave the current one intacted. I think I might not wait any longer.

Kevin,
Is your battery up to snuff? Is it staying fully charged at night? Excessive alternator heat is often the Alternator working to carry loads like a battery not holding it's charge. It can also indicate a shorted (as opposed to open) diode. Before you start up in the AM, put your hand on it. It should be stone cold. If not, current is leaking back and the field winding is acting as a load..
Which pulley are you looking for, V or Multi V, I may have one, if not both.

Battery seems fine (Red Optima), though I did have a no start after sitting for 2 weeks. It has sat longer and started fine. Thought it was the starter relay problem again. After trying a few times and cleaning all the connectors, she started with a jump. Battery had drained down to about 8 volts. She's been starting fine since, but I will check it later after it has had time to cool.

The pully in need is the V style.

Thanks!
