Amp Discharge on 52:
Is it normal for the amp gauge to show some discharge while sitting at the stop light.This is on my 1952 with still stock wiring and 6 volt system.I am afraid my wiring is shot!

Ross,it seems to get worse with lights on and brakes applied.I have posted with the problem I have with my turn signals now.At night with lights on ,brakes applied and turn signal on the signal finally quits flashing like the system is starving for current?

Well, that's about the worst case, but what is your idle speed? Try bumping it a little (like to 550 - 600). Keep in mind your truck is operating "normally", but turn signals were a new thing back then. If they won't flash under these conditions, you could try an electronic flasher (if they make one in 6v), they are not voltage sensitive. Paradoxically, larger bulbs might help it flash with the existing flasher, by increasing the draw.

I have moved the idle speed up and did not help that much.I got a new flasher and dimmer switch ordered from DC.I had posted that crazy problem with my high beam indicator also!

Hey Leoharu,
JUlie here. I remember the post on the signals and high beam switch. I had a 55 that was 12 volt but still had a generator. It was impossible for me to keep the battery charged.
Something you might look at, and I don't know how much experience you have with electrical gadgets, is adjusting your voltage regulator as well.
Ross is right and I tried to elude to this in my answer on the other post, but the electrical systems on these truck while built well, really didn't have that much electrical stuff to feed...brake and running lights, instruments, maybe heater- starter. Now with electric heaters electric wipers, signal lights (which doubles your electrical load for lights) it's a little more draw on the system. Those old generators need a few "RRRRRRs" to produce and at idle, you are probably using more power anyway ( brake lights signal and headlight). That's one of the reasons they went to 12 volt systems in 56. That and 12 volt stuff draws less amperage.
The adjustment on the regulator is done with a feeler gauge and a meter. Perhaps there is an auto electric shop that could do it for you. You will still need rpm but maybe they can get a few more amps lower down for you.
J!
