I have a original 65 lionel handcar with a bad original square two wires going to it one from the center pickup going to the rectifier (original) and the other to the one side of the motor brush
the Replacement rectifier that he sent ac to dc is 4 wires not two .. when you connect a test wires to to ac and not ground it it works but as soon as you ground it to the metal it makes the transformer hum ..
If I add a single phase rectifier the type that flows the electric on one leg it works but the performance is less than the 4 legged one
Any one been their and can tell me if I can us the 4 leged one or have to just go with the single rectifier..
I checked the original 65 handcar is dc but is grounded I think the new can motors are not grounded and I can find a way to insulate the motor from the body being grounded...
Thank-you for the info daniel
