Electrical Help Please - maybe voltage regulator

[glennpm]

I just went through a starting problem with my '32 59AB, 12 volt system described in this thread, https://www.fordbarn.com/forum/showthread.php?t=340187.


Today I was finishing up an ignition rewiring to 7mm solid core wires. With the old resistance wires and now the solid core, car starts and runs fine. The problem now is that a digital voltmeter I have down at the bottom of the firewall now is reading 0 volts when the engine is running, about 12.7 volts when not.

- I checked wiring connections to the coil and generator. I then flashed the Ford voltage regulator, removing the Field wire and touching it to the Battery terminal. I got a small spark but voltage is still reading zero.
- I checked the plug for the voltage meter and with engine running, I got 5 to 6V
- Checking the terminals when running on the voltage regulator with a VOM:
- Field, little over 5V and stable
- Generator, right around 6V and stable
- Battery, bouncing all over the place up to 18V then down to ~12V
- Before flashing the regulator, all the terminals were bouncing around quickly
- Amp meter is showing charging
- Battery fully charged


Need suggestions please.
