My dad just purchased a 53 Ford Customline and the battery is not charging.
This is a flathead with a positive ground system. We replaced the voltage
regulator and flashed the generator (pulled the field wire off the regulator
and touched it to the bat terminal) and fired it up. I has a meter on the
battery terminals while he revved it a little and the voltage didn't rise
like we were expecting it too. I was wondering if anyone could tell me how
to test the regulator. When I had the test leads across 2 points on the
regulator as he revved her up and it shot up to about 14 volts, but I am not
sure which 2 points I was on. I am not that old school and have no
experience with a 6v positive ground system and don't know which points I
should be probing on. The regulator has 3 tabs the arm the field and the
bat. Which 2 do I check on? I found a wiring diagram for 53 flathead here
(it looks pretty much
like how the car is wired), but I still just can't figure out how the
charging system works. Any help would be greatly appreciated.
If I remember correctly on a ford you short B to F to full feild. On a
Chevy you ground the feild.
The contacts in the regulator are likely oxidized from sitting. Clean
them with a point burnishing tool, fine point file, or crocus cloth
that ... and fresh metal in contact with the arse end of the regulator
housing on the side fire wall (or wheel well housing) where they affix
to each other with 2 metal tap bolts, usually half inch wrench fit.
6 volt is simple, works all the time, dumb, stupid, do it the way it
sets it self to the system of things and it will work just fine.
Yes, the contacts on the old regulator were heavily oxidized, so we bought a
new one. I guess my next question is should the whole assembly be isolated
from the firewall, or should it be "grounded" to it. It looks like the old
one had 3 rubber bushings on it to keep it isolated, but the new one we
bought only had 2 but this would connect it to the firewall.
The rubber is to quiet it down. Fastened directly to the firewall
they buzz pretty good. The rubbers should have a brass "bonding strip"
on at least one of them as the regulator needs to be grounded to
