Most starter damage is a result of heat. The heat source is the amperage drawn by the stater. The starter is going to try to develop the wattage to accomplish the starting task. If 6 volts is all that is availabe then the amperage draw is going to be high. If the voltage on the battery is low the amperage is going to increase to develop the same wattage, consequently the heat rises. When you convert to 12 volts the amperage to the starter is halved. If the voltage on the 12 volt battery is low the amperage will still be less than on the 6 volt system. The heat is less. The insulation on a 6 volt starter is adequate for either 6 or 12 volts and the wiring inside the starter is larger diameter to accomodate the high amperage of the 6 volt system so the reduced amperage of the 12 system is handled without any problem. If 6 volt systems were cabable of performing as well as 12 volt systems we would be still cranking on 6 volts. I posted previously requesting info on how to get a B Allis Chalmers to crank reliably on 6 volts and I have yet to get an answer.
