Charging issue
Hi Everyone,
In new here, love the forum! I found this site while trying to troubleshoot a charging issue I'm having. I have a '57 2x4 283 (270hp), all stock. This is in a 1931 Ford Model A coupe. Yesterday I got caught in a pretty heavy downpour (open hood) so lots of water getting on the engine, etc. I noticed as I was driving that the voltage was getting down to 10-11... I turned my headlights off and the voltage was running at about 12.
When I got home I proceeded to check the generator by disconnecting it and grounding the field terminal. (while measuring voltage on the armature.) When doing this test I get high voltage 25-30, while slightly revving) I didn't see how high, just revved for a quick second.
Without the F terminal grounded it reads about 1.5V at the Arm. This seemed to be ok so I proceeded to pick up a replacement regulator at the local auto parts store. I swapped regulators and still the same issue. Its not unthinkable that I have a bod out of box regulator but just curious If I may be overlooking something simple. I had to cut the troubleshooting short as it got too late. (couldn't sleep well then)
Any advice would be great. Thanks in advance.

There she is! Got the charging issue worked out too. Ended up veing a sketchy ground at the regulator (the generator vround wire connection to the reg. housing) got that cleaned up and tightened and good to go.
