Another charging question
This week my batteries went dead. The alternator was not charging, only
putting out about 12V. So I put a new alternator in this evening, and I
have charge voltage, 13.8V, but the alternator is way overheating. Now the
batteries are low, but I would think it should not overheat. I isolated the
two batteries and it still gets too hot. What might cause this?

Re: Another charging question
How did you start it up?
The last alternator I bought and the 'big green' (maybe the name) one my
old tenant bought both say the warranty is void if you start them up on
a dead battery.
A new alternator cannot take that amp surge until the brushes wear in a
bit, they just arc out all to crap. Arcing out means heat....
That is why some shops refuse to put a new alternator in with an old or
dead battery. The battery needs a charge to break in an alternator.

Re: Another charging question
Hi Mike,
I started it on the primary battery,,, it was about 11.8 V. The secondary
was at 9v (I am not sure about it's quality now). Once it started I
switched to both batteries. Do you think I damaged the new alternator? I
only ran it for about 3 minutes till I noticed the overheating.
