I was surfing on the net. and this guy showed how he used a 1980's/1990's car automotive charger to run his prewar engines.
All he did was put Rotary Light Dimmer Switch in the 110-volt wire coming from the 110 plug
then wired the charger so instead of putting the ends on a battery he put them to the track
His charger is set on 50 amp .. the engine he had ran very well and smooth and at low speeds crawled. He used the rotary switch to adjust speed and it worked!
so my question is this a well-known option to do or is this a mistake. my small charger only goes to 10 amps and the set up I am using is a AC kw Lionel transformer with a rectifier and a capacitor to convert it to DC I'm pretty sure its 10 amps
not sure if 50 amp would make any layout better for operation. ....daniel
