As you've probably figured out by now, your regulator is toast. You can
take the cover off and push down on the field regulator relay and see
your lights get brighter, but why bother. Replace it.
There used to be solid state replacements for mechanical generator
regulators. Probably no one bothers now since most cars have alternators.
It would be fairly easy to build one though.

Subject: Amp meter
FOT,
I've got a problem.
I'm running a stock generator and voltage regulator on a TR-4 When I
first start my car the amp meter used to go to full charge then eventually
drift back to just a shade over on the negative side and stay there. Now
it will only go to a positive charge when at an idle. I've been driving it
around town with the lights on and the elec. radiator fan on and there
doesn't seem to be any loss in power. However, when I rev the engine, the
lights do not grow brighter. When I turn on the lights and fan the needle
swings way right then comes back to almost neutral, so I think the
generator is working. Moreover, when I disconnect the battery, the car
will run on the generator, so some juice is coming out of the generator.
The generator and regulator have about 15 hours on them. Whatcha you'll
think? Richard Taylor
