I've got a new-to-me 73.5 911T. Since bringing it home (from Portland to Palo Alto), I've been attacking various small electrical problems. After today's session, I decided to go for a ride. Car hasn't been started for a month, the battery disconnect has been off, so the battery is in good shape.

Start with the usual CIS dance, but the big red charging light won't go off.

It did something similar to this 6 weeks ago when I was picking up the car from a year's storage. Then, the light stayed on when the key was off. The battery was flat then, and we towed it to a shop that diagnosed a short in the alternator. Three hours of labor and an alternator rebuild later, I was on the road.

Now this. If I was still in the same state as the shop that did the work, I'd just drive it there - but I'm not. Suggestions welcome. All I can do without tearing into the shroud, I think, is verify that there is no voltage at the regulator terminal - and there isn't (well ... my test lamp didn't light at the blue wires).

I put a voltmeter on the battery and it is not getting charge when the car is running (12.4v off, 11.8v running).

I tried tapping on the regulator in case something is stuck, to no avail. It was tested OK in early December. I checked the list in "101 projects", but it doesn't really tell me how to determine if the regulator is OK or not. It's a Marchal regulator, presumably original, which I think means I have the 70A alternator (but I'm not sure, and the paperwork I have doesn't say).

Suggestions? Maybe some connection has worked its way loose under the shroud?

Thanks,
