Check the voltage at the ignition terminal of the voltage regulator. Compare it to the battery voltage. They should be close - if not then the ignition switch could have a high resistance in the contacts.

Does your car still have the original mechanical voltage regulator? Will the voltage increase if you speed the RPM up? Me thinks you may have continuity issues now on the firewall gang connector after moving the main under dash wiring harness around There is no magic in wiring with electricity , it is either connected good, not so good or bad BTW, it took me quite a while to figure that out working for the telephone company 33 yrs, I retired long time ago in 1996 Yes a part open will cause a voltage drop and spikes. Cab, here ya go. Bet you know how to 'KICK' a wire pair.

I don't recognize that meter, what is it? I started off as a apprentice lineman and worked in pole line construction and got bore after 15 months so I transferred into customer services I&M,(installation and maintenance) for the next 13 yrs, we had little Triplet VOM to use for trouble shooting I have two of them in my shop still Along with a Fluke 87 digital VOM hat was provided to me to evaluate for field use, it works good also Direct current is very basic, no magic as long as you under stand the theory on current flow. All the phone companies I know of used A.C. for ring current and D.C. for talking on. That was over 24 yrs ago when I was RIF so I have no clue what technology is being used now, especially on wireless and Smart phones

Cab, Its a 3 wire (Ground lead) for testing cable pairs. It can be used to test Tip/Ring grounds and to 'Kick" the cable for distance. Very basic compared to what the tech's use today. 43 years in I&M but mostly Key telephone and Switching systems in US ARMY.
One wire DC circuits are kind of simple if you 'Divide and Conquer'. Split it down to sections and go 1 step at a time. Any connector is subject to failure, any ground can go open and any relay or switch can fail.
