rtjavelin Posted July 27, 2016 Share Posted July 27, 2016 re- wiring my 37 dodge, upgrading to 12 volts. the question I have is can I run a negative ground on this car with the original starter? I have done this with n old allis chalmers tractor, but It appears that I have a direct short due to the starter. I did an up grade to a 12 volt starter solenoid and voltage regulator and alternator. Will I need a new starter? if so where can I find one . Thanks Link to comment Share on other sites More sharing options...
Taylormade Posted July 27, 2016 Share Posted July 27, 2016 You're probably already too deep in to go back to the original 6 volt set-up, but with the proper sized cables, clean terminals, and good wiring, 6 volts works fine and did for many, many years. My 32 Dodge started in the coldest weather in Syracuse, New York back when I was in college and I expect it will when I finish restoring it.

30dodge35 Posted August 1, 2016 Share Posted August 1, 2016 A 6 volt starter, positive or negative will work, the way the starter is wound it will still turn same direction, voltage amp direct portion, 12 volt lower amp, 6 volt higher amp , need larger cable, main thing I fine 12 volts spins faster and bendix engages faster, may shear , i have been running 6 volt positive ground stater on 12 volt negative for years on cars and tractors, only problem was bendix.
