Should alt be drawing power? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I converted to int. regulated alt. When i did the conversion, i cut off the clip that used to plug into the regulator. I spliced the brown and white wires together and the pink and blue wire together, and ran a length of the new white and blue wires to the alt. I now have three wires hooked up to alt. One red one (hooked into the back of alt from harness firewall connector), one blue and one white from the splice location(the two wires are together in a clip that clips into side of alt ). When I hook up my wire to battery, the blue wire becomes energized, even though truck is turned off. I have even unhooked the wiring harness from the firewall and still the blue wire is energized. Is this a problem or should it be like this?

What type of plug did you use from the port on the new alt.? I'm not sure exactly what you are doing, but with the adaptors that I have, you do not wire those wires together, you just use a jump wire from I to F on the old regulator plug. The white wire coming from the dash side is the switched lead wire that you should wire in to using the adaptors that I have. Sounds like you are doing things backwards to me.

on mine i ran the black wire to the alterantor case, the red wire from the clip to the battery post, the brown wire to the white wire, and ran a new wire to the bateery junction block. took out all the other wires. been working better than ever for a year.
