Alternator Grounding??

[ben swann]

Yes the alternator is hgounded through its housing.  I would not hurt
to check all your grounds, especially the one behind the bellhouding at
top rear of engine, and run a dedicated groung of at least 10 Guage
directly to the alt. if one is not already there.

The little blue wire is the feild exiter wire and is not a ground -
refer to the wiring diagram for you car for details.  Most use/take
this micro current to power the alt. light momentarily when engine
started and use it to "excite" the alternator into operation.  If that
conection is bad, alt. most likely will not work.

I had an alternator go bad this last weekend and while I was installing
it's free replacement (thanks NAPA) I started to wonder about having a
ground wire for the alternator.

On my CGT all I have is two big red wires going to the same terminal
and one small blue wire which I am guessing is not a ground since it
goes into the dash...

Am I missing a wire?   Would a ground strap to the block help? hurt?
Does the alternator ground through it's housing?

Thanks
