Thanks Joe (et al others)!
I've posted the same question on the National Vette Forum and I'm getting tons of advice and suggestions. Only with this car can you find such help from the nicest car owners out there!
I think I may have found the issue and that is one of the wire leads (positive) coming off the alternator has simply rotted (corrosion) away from the threaded stud.
I ran out of daylight before I could get the fan belt back on. I'm still taking the CE into the dealership to have a full dioagnostic performed to see if I've chuncked
any ECM codes/modules.
