    No, not that I am aware of. The 6V units will run fine on 12V if you don't crank them to death and it is harder on the bendix springs. They are Delco Remy motors which probably could be converted to 12v by changing field coils and armature and possibly shafts.

    It helps to install wider brushes in the 6 volt starters for better cranking.

    everything is complete including the VR. the starting motor works fine and the pony starts right up no problems. has the 12 volt batt done any damage to my charging circuit ?

    Default charging system damage ??

    Not likely ,it would just not charge as the regulator is set to cut out out at about 7 volts ,
    putting a 12 volt battery on is a sure sign the person hasn't a clue about basic electrical repairs
    as these delco motors work really well on 6 volts if the battery and the cables are all good and the motor is ok....

    Thumbs up

    $118 isn't a bad price, I think the NAPA 675CCA in my John Deere B was right around the same price (a year or 3 ago)?
