Guys, I'm trying to help my father in law figure out a current draw problem in his 54 model Cub which has been set up with a small Hitachi alternator and what looks like an old Ford four terminal voltage regulator. This unit charges the battery in the 13.2-14.6 volt range everytime I've tested it with a DVOM. When the engine is shut down the field coil inside the VR stays powered up causing a 0.3A draw on the battery which over a day or two in cold temps causes the battery voltage to drop to the point it has to be jump started. I think the problem is due to improper VR/ Alternator connections. I have searched the net all over trying to find a correct wiring schematic for the VR but I come up out of luck. I hope you gentlemen can bail me out. Thanks!
