hello all....

i was jus wondering how many ppl have swapped from a external generator to a newer style alternator like the 1 with the gmpp serpentine kit?

i have a few picz, but my problem is that i cant seem to keep my battery charged an i was wondering if my alt was wired correctly......


in the last pic i ran the screw on back to my battery for constant power but is that where i messed up? does anyone have step by step instru.? or know of a site?

The big red wire goes onto the 1/4-20 bolt that comes out of the back of the alternator. It looks like you have it connected to the field windings (they should be the smaller blue and white wires).

The white and blue go to the lugs on the top of the internal regulator with blue going to post #1 and the white to post #2 (Assuming you have a three wire SI style alternator instead of the newer CS with four top lugs). You then remove all of the wires from the external regulator and splice the red wire to the white wire. You then splice the brown wire to the blue wire.

If the motor will not shut off after performing this little bit of surgery (It should); you will have to slice in a diode to prevent the charging trouble lamp from back feeding the ignition circuit.
