I copied this from a 1931 Flamingo thread on hard starting. DD had this in the post.

Now, with ALL wiring connections verified, let's attempt to polarize.

First, remove the BATTERY CABLE connection at POS BATTERY post. This will take any power off of regulator, like starting from scratch.

Now, re-attach CABLE to POS BATT post.

DO NOT turn key on! DO NOT crank engine!

CAREFULLY, remove the "FLD" wire from terminal on regulator. DO NOT let it touch any metal surface.

Carefully, take the end of "FLD" wire and briefly TOUCH it to the "BAT" terminal on VOLTAGE REGulator. Do that a couple of times. You should see a slight spark each time.

Now, carefully re-connect the "FLD" wire to the "FLD" terminal on voltage regulator.

PLEASE...Follow these directions explicitly, and IN ORDER!

Now, crank-up your engine and tell us what your results are. Hopefully, all will be normal. If NOT normal, it's likely that your regulator (or generator) is damaged internally.

ANY TIME you work on GEN or REGULATOR circuits, you MUST re-polarize. It also won't hurt to re-polarize any time BATTERY is disconnected from circuit.

I have been looking at this older thread. I have put a new battery in the 48
(6 volt) and after running for awhile the battery doesn't charge. I see that DD is saying that each time the battery is disconnected from the system it must be re-polarized. I have never done this at each disconnect. Would this mean that if one has a battery disconnect switch installed they should re-polarize each time it is turned off? When I leave the car parked for long periods I disconnect the battery. Could I have damaged the generator or voltage regulator by not re-polarizing each time I disconnect? Should it be re-polarized each time? Obviously I'm not an electrical trouble shooter.
