70 r.r. voltage regulator

i have a 10 of 69, 70 r.r. that uses the 69 and older voltage regulator. factory wired, is this common? Factory shop manual shows electronic regulator

Electronic regulators began to be equipped on some late big Chryslers/Imperials. As far I know these regulators were with 3 terminals ( dunno whyc ), so I find hard to think on 70 models some cars still were able to get mech regulators? Dunno.

My bets are someone replaced the harness. Never seen or heard of any factory wired that way.

Agreed...never seen a 70 with the older regulator.

factory voltage regulator mounting holes for older regulator, not factory drilled for newer style, i would have to drill holes into firewall to mount newer style

Something seems questionable here.....by 10/69 they were 3 full months into the 70 production year.....having a 69 and earlier voltage regulator bolt pattern on your firewall is very suspicious.

70 parts and service manuals do not show anything either. All show the electronic style and alternator. I would like to see the car and all the body numbers.

If you remove the electronic voltage regulator bracket,the early regulator bolts right on.

Right. But the poster does not have that. He most likely has a old harness that was installed. His car originally had this mount.

My 70 GTX was a August 24, 1969 spd, Lynch Rd build and had an electronic regulator.

where would you find that bracket, i have found several strange things on this car, hood mount turn signal wiring only had tight side connection

That's because someone had their fingers in it and made it work to their liking. So nothing makes sense because nothing is original.

thank you so much for your help
