I just had the generator rebuilt for piece of mind. Do you need to polarize it?


I just purchased my 1953 Chevy 3100 three weeks ago. So far I know it has a 235 ci six-cyl out of a 54 passenger car, converted to 12v, not sure when painted, Coker bias-plys, 3 on the tree, nice interior, no radio, guessing 4.11 rear. Had a lube job, drained trans & rear. Added new fluids. Replacing VC gasket/ Old one fell apart in a dozen pieces, hence oil leaking. Does not smoke. Will drain coolant system & replace thermostat. Ordered an Assembly manual. Have a 48-53 truck shop manual. Will replace plugs & wires. Had generator rebuilt.

Wouldn’t be a bad idea and causes no harm
Momentarily connect the armature to battery positive (assuming it’s a negative ground system)
One second of contact is enough
It’s gonna spark

If it’s a positive ground system then the armature gets a blast of negative

Redbird,

After looking at some of your other posts, you seemed to previously indicate that your truck is currently running a 12 volt battery system.

When you had the "generator" rebuilt, did the rebuilder know you are running 12 volts and not 6 volts?

As others have noted, your '53 was originally a 6 volt system when new, but appears may have been modified to 12 volts (not uncommon) at some point afterwards.

You may want to confirm your generator is a 12 volt unit before going too much farther.

Well 12 or 6 volts will polarize the system properly
If the polarity is correct
After that yeah all bets are off if the regulator and generator are not Matched to the battery smile

It works for heat riser valves, right?

Hey Jerry. I think you meant to answer my other thread. This one was on polarizing my generator.

I'm just applying your logic on disabling components that engineers spent millions of dollars developing. If it works on heat risers, why not generators? I spent 30+ years teaching automotive subjects at the high school and junior college level. Your heat riser opinion doesn't make good nonsense. You've already gotten the correct advice on polarizing the generator. Do it.
