Did you take the ground from the harness and ground the case?

Not quite folowing on the blug wires here...I put the blue wire to the red wire on the new pigtail..then the white to the brown.
you have the old reg harness done right from the sounds of it.

Check the back with a screwdriver...hold it by the center where the bearings are at. It should have a magnetic area while running it the thing isn't a turd.

I got 3 bad alternators in a row last year. This drove me crazy. I wouldn't believe anybody that told me that, but I can tell you first hand it did happen!. Make them take your New rebuilt alternator out of the box and test it BEFORE you leave the store. I did this on the last one and have had no problems since.

71Chev · 04-23-2002, 08:27 AM

Are you checking it with the engine at idle?
Kick the rpms up a little, what does it put out then?

I too had a "new" alt that was bad. Just because a part is new, doesn't mean it's good.
