I need confirmation on the Tech Wiki section regarding the alternator conversion from external to internal voltage regulator.
I have a 19171 B110 (1200 coupe) with the old style 35 amp alternator with the external regulator that is causing way too many voltage spikes that affects my EFI injection pulse widths. The attached wiring diagram was taken from the Tech Wiki section and shows the wiring conversion for the B110 (smaller portion of the wiring diagram on the left hand side of the attachment.
The smaller diagram shows a red dashed line coming off the "S" lead off the alternator with a note "factory B110 harness". Is that referring to the factory "T" 2 wire harness or does this wire connect to another wire inside the 6-wire engine regulator harness?
I really don't want to risk burning up my electrical system by making a wrong assumption.
BTW, I will be using a 50 amp alternator, AC Delco PN 334-1578.
Cheers
Roger
