The '32 has been a driving car for probably five years now with only one previous charging problem, which was cured by a new voltage regulator. Now I've got a new problem and can't find the cure. It's a flathead with a late '50's/early '60's 12 volt generator with a '40 Ford front mount stuck on it. The car is wired using a diagram from a '60 Falcon. I was driving it Friday afternoon around the fairgrounds at Back to the Fifties and had noted it was charging according to the amp gauge. But going back to the hotel that night with the lights on I didn't see it on the + side. I didn't think much of it since the headlights and high-power taillight bulbs always pull lots of juice. Saturday morning it had a very weak battery, not enough to start the car. We jumped it and drove to the fairgrounds, but by the time we got there it was running rough. I thought it was the battery not able to hold a charge (six year old battery), so we bought a new battery and put it in. But the amp gauge would still not show a +. At home I removed the voltage regulator and noticed a little bit of pit transfer on the points on the battery terminal. I replaced the VR with a NOS Holley/Standard VR21 and took it for a drive. My brother and I watched it charge a lot at first, then settle down to just a couple + amps when running. We tried the headlights and it would be slightly on the - side, which is normal. We figured just to be sure everything was working right, we'd do the "pull the battery cable" trick. I pulled the - cable while the car was running and it shut off immediately. Crap. That means the generator is not working correctly, right? I pulled off the shelf a used generator that was previously corfirmed "good" by my local hole-in-the-wall shop. Switched the correct front mount and pulley onto it and cleaned the dust and dirt off of it. Installed it and started the car, happy to see it charging on the + side. Then I unhooked the negative battery cable and the car died instantly. WHAT IS WRONG? The wiring was new five years ago. There is a direct 10 gauge ground wire from the generator to the VR, then to the body. Another ground cable from the body to the engine block. Battery grounds directly to the lug on the torque tube clamshell. Yes I've polarized the generator every time I unhooked and reinstalled a component. All these new parts, and the car still dies when I yank the negative cable. Where could the problem be now? .
