Tom, What would cause the alternator belt to slip if batteries
indicate they are fully charged? And why do batteries except a full
charge so quickly? Your example assumes the battery bank still has a
capacity of 800 AH and is in good condition.

Richard, I think that was Wayne's post you were replying to. But,
thanks for the cases. They are interesting and scary. I'm afraid that
I am still missing something though. The belts have to be up to
dealing with the rated loads on the alternator or the system will
never work right. There should be fuses protecting the alternator
wires. So how do you set up a belt to protect the system and also
have it accept the full alternator load in the no fault condition?

As to your questions, belt slip can be caused by lots of stuff
including bad bearings, bad belts and loose or bad brackets... Having
the batteries come up to full voltage quickly does suggest to me that
the bank has a fault.
