If the tach motor is wound bad and starts turning at a very low voltage, the board things speed is fine and does not raise voltage. It does not know the non tach motor is not spinning. Basically the tach motor turns at too low of a voltage. As I said I found this imbalance on 2 PS-3 diesels. Live testing can be risky. Touch the chassis with a lead and you can have poof. G

Pretty sure it’s this one. No matter what motor I connect to the non tach motor leads it won’t spin a bit at the low voltage that the tach motor spins at. Ugh
