The po wired in a 10si. #1 goes to idiot light via the factory brown wire. #2 goes to starter batt term . Alt Batt term goes to starter batt term . Starter Batt terminal goes to + side off battery, from there to the horn relay.

The idiot light comes on and slowly goes dimmer with increasing RPM. Is this an idication of a bad alt or bad wiring design?

Valiantsignet200,

The wiring is proper. My guess is the brushes are worn and not making contact with the slip rings...either that or there is lots of dust and dirt in the thing. This has happened to me before. Try blowing the alternator out while it's running.

You have a bad diode trio in the alt. They are not hard to repair yourself if you get a book & follow the instructions. The diode costs less then $5 at a parts store.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
