[DeTomaso] Ammeter and voltage regulator question

[Larry - Ohio Time Corp]

Dan,

The noise is the belt slipping. 100 years ago when I was in auto tec the
teacher told us when we hear hoof beats think horses not zebras...

Pick up a new belt, and then tighten (not with all your strength) the one
you have on it now. Take your tools and the belt on your trip to be safe.

I've had the cover off but I forget if I inspected the belts.
Come to think of it, I've heard a squeaking back there on occasion.
I was wondering if it was the water pump bearing but it could be
the alternator.

That's the plan for today after work.

I cleaned the battery terminals and the ground in the front trunk.
The car would barely start when I got it but it now cranks over fine
and starts immediately.  I'll check the ground at the back too.

Okay.

Will do.  I was planning on driving it 100+ miles tomorrow morning
to check out a Mangusta for a possible buyer.  The Mustang is on the
lift, waiting on a fuel line fitting to come in from California.  I
could take the TR8 but it's got an annoying lifer tick (previous
owner installed Rhoads lifters) that I need to do something about.

Thanks,
