A '95 used a 1116411, 425, 437 Delco reg which could not turn on without stator latent signal. The 10MT starter was old school. But the ECU PROM was fed battery voltage to keep memory settings. Isolate the PROM power, and every start was a computer re-learning curve. Neat huh? The voltage regulators above fit both the CS130 and the CS 144 alternator. Late 1980's CS alternators did not bother using a 270 ohm resistor in the PLIS "I" terminal which burned out the original 411 voltage regulator. This was a factory GM chassis problem.
