Generator light staying on
Fired up My '59 today, so I could see how it moved back and forth thru the gears. The generator light is staying on while the engine is running. What is the problem,and how can I fix it?

unplug it...kidding
sounds like low volt/amps from battery-is it through all RPMs?
do you have a volt or amp meter in truck? someone else will be along to tell you how to test without these if you do not have in truck

Yes, it is thru all RPM'S, battery is only 3 months old. Just has the idiot light, no gauge. I just can't get a "charge" out of electrical problems

I had to replace a couple cracked ends while I had it off when I was cleaning and painting the engine. are there any fusible links on these? I'll check the wiring over again for any more damage

The generator had been overhauled as it had the sticker from a rebuild shop, and regular appeared to be a recent one. I did not polarize it,after repairing the ends, how do I go about doing that?

On a Ford, disconnect the Field and Batt wires from the terminals at the regulator and momentarily touch them together. You should see a healthy blue spark. That's it.

Never say never, but polarization is normally only required if the generator itself has been disassembled or maybe if it has sat for a very long time.
Simply disconnecting the battery, or replacing a regulator, isn't cause for that. It's important to use the technique for the type of generator involved. Ford is different than Chevy, etc. The method outlined is from the 64 Ford Truck shop manual. It goes on to warn that other methods may burn contact points in the regulator.
