As our late, great sparkie-meister Dell used to say,...if it won't run on 6V, what makes you think it will on 12V?... There's nothing wrong with 12V, nothing wrong with 6V either, just be sure you know how to wire each correctly. FACT: 99.98% of all non-starting issues are due to incorrect wiring and many 12V conversions are done wrong. On our FORD's many use the road worthy DELCO 10SI 1-WIRE ALT. YOU DO NOT NEED A 12-V Starter Motor. that is a fallacy. Starters don't care if 6V or 12V. On a 12V conversion the Generator and Voltage Regulator (or CUTOUT) are removed from the circuit altogether. The ALT is then installed and OEM wiring can be modified or invest in a new harness for 12V. With either a GEN or ALT, you MUST use a belt tensioner bracket otherwise you will never charge the battery. Original GENs like on FORDS come with a belt tensioner. An ALT will need a special one, the OEM GEN won't work. Be aware all 12V kits do not include the belt tensioner. You may have to get a new pulley and fan belt, size matters - either 1/2 or 5/8, ya gotta know which ones. If proper fan belt tension is not maintained, you will never charge the battery, can damage the water pump, power steering unit if you have one, and cause overheating and damage the radiator. If you keep your original 6V Coil, you will need to add an in-line, external 1-OHM resistor or equiv in the coil circuit. Delete the extra resistor (my choice) by swapping out the 6V Coil to a verified 12V Coil. You do not need a fancy 40kw 'Flamethrower' Coil. How much do you think the charging circuit requires? Finally, you will need to swap out your lamps. Industry Standard part numbers for the Sealed Beam Headlights are: 6V = #4019 and 12V = #4419. FORD Taillights use the bayonet-style bulbs: 6V = #63, and 12 volt = #67, '39 - '64. With a 12V conversion, if you leave your 6V headlamps in, the second you power up you will smoke them. I can't say how other makes were wired but probably same or very similar.
6V & 12V CONVERSION EXAMPLES:
FORD 9N/2N; FORD 8N, FRONT MOUNT & SIDE MOUNT; 6-VOLT:

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
