I've got a 60 Lark VI retrofitted with an alternator and Chrysler voltage regulator. My question is, does the regulator housing need to be mounted to the frame (grounded) or isolated from the frame? I ask because I replaced it along with a bunch of other components the other day, and when I got my car started--a miracle, if you follow my other threads--my headlights would flicker and my idle was slightly slower when I mounted it to the frame, but it smoothed out and the flicker went away when I isolated it. The old one didn't do this before, so I reinstalled it both ways, and it has the same symptoms now; clearly something changed when I replaced the solenoid and ballast resistor. Before someone asks, yes, I made sure that all my connections were correct when I swapped those components.
Now, since then, I have had my battery tested as bad and replaced it today along with my battery cables. When I ran the car, the battery voltage only read 12.5v, even while revving higher than idle. Since then, I discovered that the ground wire on the passenger side, for the engine, was missing so I installed a replacement. I haven't had a chance to retest the alternator since, thinking I might remove it and have it checked out, but after finding the ground strap missing, and testing resistance before and after--a change from a 1-15 ohm reading to a 0.1-0.5 ohm reading--I'm wondering if I should reinstall the regulator to the frame.
I have tried to find opinions elsewhere online, but found conflicting information. Anyone care to share their insights?
