Hello everyone. Does the 1974 Case 444 use a proprietary voltage regulator for this tractor? I have replaced the voltage regulator (quality aftermarket 4 post) , condenser, coil, spark plug & wire, points, battery, solenoid, and had the starter generator rebuilt. The only part that hasn't been replaced is the key switch. I am still only seeing 12.28 volts at the battery with the engine running full throttle. The field side of the S/G housing is also getting very hot. It's acting like it's backfeeding into the S/G and not letting current pass through the voltage regulator . I'm stumped at this point. Any suggestions would be most appreciated.
