Remember also continuity check on exciter wire, I think it runs to / thru terminal #1 on 14 pin.

If it's only the exciter circuit..all he needs to do is rev over 3500 to get it to start charging... good luck

What's that Chris? Not familiar with that wire or its function.

It puts a load on the alternator to establish a field. There is a resistor in the pod that provides this function.

I know this sounds stupid, but I have 1 amp direct charging solar panel in the hatch area, just to have a constant extra 1A laying around on bright days.

I got the car to a Bosche authorized service center - place called Classic Import Repairs. Not sure if it's the same contact you have Donald. This shop looks good, and he has at least 8 or 9 P cars in there, including 2 912s, Boxters, a 968, and several types of Carreras. He told me he owned several 928s in the past. I believe him (have your guy call me anyway Don in case this guy can't get to it today I'm at four-oh-six-581-73one-six).
He tested the post, and the charge is 12.2 volts, and it isn't charging. The alternator on the car is a rebuilt Bosche unit, put on last year in May. When it was installed, the meter on the dash showed only 12 volts, but the po told me that the charge measured 14 or so at the alternator post. The mechanic told me this is common? Not sure why it would dod that. Anyway, I ran for over a thousand miles and 2 days, and the needle never moved off that reading until last night - the battery stopped charging.
As to driving with extra batteries, no way will I do that out here - this is the most remote part of the country I have been to. From this city to Rapid City is 333 miles, with absolutely nothing in between. Same as the next leg to Billings, MT. Once you're past Sioux Falls, you're screwed if you have a problem. So here I'll sit until it's fixed
I'm lucky to have found an apparant qualified place tho.
So it stopped charging -- not an overcharge condition as mentioned in the OP. The voltmeter in the dash may not read correctly, usually due to resistance in the many connections between it and the battery. Mine, when tested out of the cluster, was almost dead-on; with connections cleaned it is very accurate. Anyway, with a no-charge condition it could be a number of things, but it sounds like you're in good hands.

As to the pod cluster light, I never noticed that with my other sharks - so it stays lit all the time? Why? Wouldn't this burn out the bulbs? It does go out when the key is off.
I guess they stay on so you can see the gauges any time the engine is running, e.g. you get into the car in the dark and start it up, you don't need to be showing any exterior lights to be able to see the cluster. The owner's manual describes this behavior but doesn't offer a "why".

Actually, this was added in '81/82 IIRC, Ed's car won't have it unless it's been added. There is a TSB on this.

Ok folks, Ed is up and running. Something about loose alternator wires and it being an after market alternator.
I will let Ed tell the whole truth, and nothing but the truth, when he is able.

He siad to pass on a ton of thanks to all.................

Speaking from experience, there's no better feeling than to be back on the road after being stranded. God speed, Ed but watch out for LEO while you're trying to make up that lost time.

If you get a reading of 14V at the alternator, then go back to the battery and check across the terminals. If you get 13.5+V, drive on and be happy.

George Suennen's car has a problem with the dash gauge reading below 12V with the car running, regardless of RPM. We checked everywhere in the car (jump post, various red wires on the CE panel) and got at least 13.5V. So, George bought another volt meter. It reads below 12V too. So, we checked the wire at the back of the meter and got 13.5. Go figure.
