He will need to get a voltage reducer for it, either one or more resistors or a 6V power supply, or he will need to swap out the motors and other electrical parts like ignition coils and heating elements with 12V parts. To calculate resistors, you need to measure the current draw on 6V, and use Ohm's Law: resistance = volts / amps. For a 12V system, you would use 6.3 V for the volts you need to drop across the resistor. The wattage rating of the resistor would be amps squared times the resistance times two, to give a safety margin. You use the same fuse amp rating as for 6V.
Digi-Key http://www.digikey.com/ or Mouser http://www.mouser.com/ are good places to buy resistors, if the local Radio Shack does not have what you need. I wonder how much of a market there is for 12V to 6V converters? The design is pretty simple, and I am an electrical engineer... :) Chuck Kuecker On 6/28/2011 11:32 AM, Timothy Osburn wrote: > I have a friend who is converting from 6 to 12 volts.
