Re: Alternator help needed

A: The "I" wire is indeed ignition (on/off with the key) IIRC, they went 
FIBS (Field, Ignition, Battery, Stator) The "S" didn't need to be hooked up 
(it goes to the light in the dash), but the regulator needed to be grounded 
well and if you didn't have a ground wire from battery to body, it wouldn't 
charge with the lights or anything else on.

 I have switched all my AMCs over to Delco type/single wire altenators and 
have had no problems for years.
