Ive got a '69 camaro rs/ss, Ive just put the engine back in after a rebuild, replaced some cracked and poor wires. Somehow, some-way, i can't seem to get 14 volts. Ive also mounted a Ford starter solenoid due to heat on the firewall. Its got a MDS ignition now, and ive wired it just like it was before the engine was pulled. Is it the Voltage regulator? I have confirmed that the alternator does work on another system. Do newer alternators have internal regulators? If I put a New alternator in, is the voltage regulator obsolete?

Any sort of input on some of these questions is GREATLY appreciated.

Assuming that everything else in your electrical system is correct, it sounds like the external voltage regulator is bad....especially if the alternator worked on another car. I would double check the wiring to the alternator and external voltage regulator though.

The 12SI alternator is a good option if you want to upgrade from your original externally regulated alternator. The 12SI does have an internal regulator so you won't need your external regulator anymore. The one that should work for you is an alternator for a 1984 camaro which would make it a 94 amp unit with a 3:00 clock position.
