Car Forum / Antique and Collectibles / Antique Cars / March 2005HELP? 6V Pos Gnd to 12V Neg Gnd Conversion
I have a 53 Dodge Panel truck which is a 6 volt, positive ground system. Now I don't care about the guages, lights, as I will change over to 12v neg ground parts (saving the old ones of course) but what the hell do I do with the starter? I can adapt a simple alternator to the engine (probably) but can the original starter be converted to 12V negative ground? > I have a 53 Dodge Panel truck which is a 6 volt, positive ground system. > > Now I don't care about the guages, lights, as I will change over to 12v neg > ground parts (saving the old ones of course) but what the hell do I do with > the starter? I have been told that the Ford 6 volt starters work very well on 12 volts -- they just turn more rapidly. Reversing the ground will not make any difference in the direction of rotation.

The old starters are series-wound, which means they rotate the same direction no matter the polarity of the supply voltage. Probably tens of thousands of old Mopars and Fords have been changed to negative ground simply by reversing the battery and ammeter leads. The starter will turn faster, and with more oomph. You want to be sure the starter drive is in good condition...if the starter "freewheels" because the drive doesn't engage properly, it may spin fast enough to throw solder and windings. If it does, just take it to a real auto electric shop and have them install 12 volt windings. Till it does, (which may be never) just use it. Joe  SignatureHeather & Joe Way Sierra Specialty Automotive Brake cylinders sleeved with brass Gus Wilson Stories http://www.brakecylinder.com I have a 53 Ford that I converted to 12 volt and left the 6 volt starter alone. I figured it would burn out eventually and then have it converted to 12 volts. 5 years later its still going. Ray >I have a 53 Ford that I converted to 12 volt and left the 6 volt starter > alone.

I'm going through this with my '55 Studebaker coupe, and a '56 Hawk wiper motor is a drop in. Also replaced the defrost blower with a '56 unit. Still trying to find an early Hawk heater blower. nate Signaturereplace "fly" with "com" to reply. http://home.comcast.net/~njnagel > >>I have a 53 Ford that I converted to 12 volt and left the 6 volt starter > >>alone.

Wiper motors were vacuum but i used an electric one that replaced the vacuum on in the 53 and was 12 volts. New Port Engineering, but dont know if they have one for Studebaker. Heater motor is 12 volt from a 65 mustang. Ray >>>>I have a 53 Ford that I converted to 12 volt and left the 6 volt starter >>>>alone.

The OP has a '53 Dodge panel truck. George Patterson Whosoever bloweth not his own horn, the same shall remain unblown. |
