Experiencing electrical failure

[Shinto]

I put an oscilloscope on the alternator output while the car is running. There is a small noise component present, but it nearly didn't register. No DC and negligible AC signal.

Every place I've looked it seems to be special order (not a huge surprise, but still annoying). I called around the dealerships and one thinks he can have it today... Of course the price is considerably higher than a rebuilt ($250+tax and $18 core), but on the flip side, its new and I can have it today (maybe). BTW, the parts guy said that the part has been discontinued by GM, but there are about 14 left in the various zone warehouses.

Greg: That's the best news to come out of this whole episode. I really didn't want to get that far into the motor without replacing coils and injectors, but of course can't afford to do either right now.

Pete: That's the best price I've seen so far. Unfortunately, this is my daily driver and I need the part asap.

Tom: I'll give you a call as soon as I can procure the part. I may (or may not) have all the tools needed, but haven't dug this far into the engine before and don't have anything more than a generic Haynes manual. All my books on the ZR-1 and the LT-5 are in storage, so I don't even have a decent cutaway or exploded diagram. Your first hand knowledge could save me lots of time.
