'49 Suburban 6V system
When I touch anything with electrons, it scrambles my brain ........... so bear with me !
Last week started the car, voltage regulator started clicking and ammeter jumping around then settled down and started working. Drove it several times since, same thing after start, then works properly. Pulled the regulator and found a burnt place on one of the windings. When looking for regulators I noticed some were positive ground, some were negative ground. Looked at the car, it's negative ground, so bought a Borg Warner negative ground.
Previously, after starting, the ammeter would go to the discharge side until it ran for a few minutes to recharge battery, then back to zero. All the electrical on the car works great.
Installed the new regulator, polarized, then started car. The ammeter now goes to the charge side ! Got out the service manual and noticed it's a positive ground system !!!!! ???
) When charging should the ammeter go to the discharge or charge side ?
) When the car was changed to negative ground did they leave the positive ground regulator and the ammeter was displaying opposite ?
) Is the new negative ground regulator the one I should use ?
I put the old regulator back on and all is as it was, just clicks a few times at first start
Thanks in advance for the help,
Don
