M rewired, fired up, blew starter on restart

Folks,
Recently rewired my '51 M for alternator and fired it up yesterday...Vrroomm! As I was basically running without any gas tank ('cept what was left in the carb) I needed to shut down. Several hours later I returned to restart the M with a better fuel supply but all I got what a sold thud (sound maybe like started solenoid?) and then my makeshift idiot light went out and I had no power. My battery checked out at 12.56V afterwards - up substantially from the 11.0V prior to first start. When running the new ammeter seemed to hit ~20amp mark (amp scale large at +/- 60amp). My batter to starter cable appears larger than the usual 12v cable, might still be O.E.M from 6v days. Starter is a remanufactured 6v. Front and rear headlamps wires were disconnected due to condition. Light switch was in low or dim position. (Which way is OFF? Decal in worn away and only partial lettering can be seen.) Is there a dimmer resistor which I can replace made for 12v, if not, where could or should I place one? Are there light switches made for 12v systems and would that be more appropriate? Lastly, is there an in-line, smaller-sized resistor that can replace the newly installed ballast resistor?
All help and comments appreciated. Thank you in advance.
