Looking for some wiring advice.

I'm still undoing what the "top-notch" local race shop did. I have a later alternator on the 2.5 (anticipating when it will go in the GT and drive many big lights up front). The 2.5 is currently sitting in the 911 while I get the gumption to build the 3.0 MFI motor.

The problem is, the dash (old generator) light is on 24/7.

Anybody BTDT with a later alternator in the generator slot?

I'm not aware of a generator ever being used in a Porsche six. There was a change where (Late '70's???) the alternator went from being externally regulated to internally regulated. There is a tech bulletin on that that I have if that's what you have going. Somewhere (Pelican?) there is a great description of all of the possible scenarios of the dash light being on - or off - when it shouldn't.

You have to put in the whole enchilada, fan ring, fan, and alternator. Just dealt with swapping an early (2.7) fan ring into a later car, and it involves cutting the alternator support part of the ring to take a later alternator. Late fan rings are NLA (this car's an '87), and any used one you find is apt to be cracked, according to the guys at Parts Heaven. The Cap'n

Eric does your belt track straight (or perpindicular to the crank)
If it dont like the Capt. says you need the ring machined deeper.

Straight as an arrow. I already have the entire enchilada meal deal in there. The shop just buggered up the wiring. I have two more complete assemblies on the shelf as well. I'm almost as big of a pack rat as... well, you know who you are!

(IMG:style_emoticons/default/av-943.gif) I doubt that... maybe I'll come out there and tell you if your close (IMG:style_emoticons/default/wink.gif) and I really don't know the full extent of who you're reffering to either... just the surface (IMG:style_emoticons/default/aktion035.gif) Where I hope to be when I grow up (IMG:style_emoticons/default/laugh.gif)
