Alternator problem, Part 15...
Just installed my freshly rebuilt alternator (from a reputable shop) on my 1982 SC, and it still isn't working. Upon start-up I took the revs to 2K and received a reading of across the battery terminals of 12.02; left car running for 15 minutes and sure enough the reading across the terminals was down to 11.88.
The battery is less than a year old and was fully charged. What gives???????
DE season is coming!!!!!!! Arghhhhhhhhh.....
Suggestions please.....

I would ask them if they bench tested it before returning it to you, if they did you must have it hooked up incorectly. Just an fYI I did EXACTLY as you have just done yesterday. Put in my rebuilt alternator and got 11.8 volts on runing with the alternator on. The one thing I was concerned about was one of the connect ors was just a push on connector ( for the brushes ) ( I have an external regulator ) . When I took off the shroud again there was the wire hanging. With all the twisting to put that F-ing shroud back on the wire had simply come off. I put it back on much more carefuly and all is good.

I feel your pain ... I just did it yesterday and the back of my hands are pretty cut up. But think yourself lucky. I think your car has three nuts holding on the shroud, mine has all six. Do you have a bently for the connections ? I can help if you don't . I think all your wires are screwed on but if not try just loosening the shround and peering in . I got lucky with mine ... Don't be too upset .. if they bench tested it and it works I would in=magine it is something fairly simple .. but if the car is a daily driver .. what a pain ...

Not a daily driver but my (broken) toy...All my wires are screwed in..yes, 3 nuts on the shroud. Everything has to come out (again)...Thanks!!!
P.s.-I measured the voltage with the engine off -12.27......

Well yours is a later car so the regulator is built in . The only other thing I could think of would be broken or frayed wires.. according to the bently there is only 3 wires . B+ to the battery.,D+ to the warning light and D- to the electrical . But my bently does show to push on wires coming from the regulator in the photograph. If that is the case I would be checking them first ...

PS I was so annoyed late night I decided to dive right in . Whipped the belt off, took the two 10mm bolts off , took the two 13mm nuts off of the coil, loosened the strap , undid the 6, 8mm nuts .. 15mins and I had it out enough to check ... I have this thing out WAY too often ..
