High Oil Pressure

[k hutchins]

I'm sure you've already chkd, but just in case.
I had a problem not charging as well. It turned out that my belt had stretched and wasn't at the right tension. Tightened the belt and applied some belt dressing and all is well.
Good luck

I'm suspecting either the generator itself or the voltage regulator. Gauge works as it should, battery is new.

Might as well get used to pulling the gas tank now.

Hi,
A 1948 Cub would have originally had a cutout, or Relay, IH called it, on top of the generator.
It's not a voltage regulator, you had to select the rate of charge yourself using the Low or High charge switch on the dash. That is a 4 position switch, it has the light switch in it too. It should still have the 4 position switch if it has the relay. There is probably a set of points in the relay, they might need filing and cleaning so it will work, points get burned and corroded over the years, and need cleaning.
Here are pages from the 1949 Cub owner's manual showing how the system looked originally. One page tells about the 4 position switch.
