6 to 12volt conversion

Postby techjake4690 » Sun May 20, 2018 9:08 am

good morning All,
I recently bought a farmall super C for my farm and would like to convert it to 12volts. I worked on cars and now currently work on Semi trucks so rewiring it shouldn't be a issue. so my question is can I keep all the orgional wiring the same the last guy to own it installed a new wire harness on it. the other question I have so Im going to delete the generator, regulator and install a alternator. delete the 6volt battery gauge and install a 12 volt gauge. I noticed some people install a resistor and keep there old points and coil the same. should I go that route or should I install a 12 volt coil and points and not have the resistor? if you have a second to help a farmall friend out that would be greatly appreciated.
Thanks
BIG JAKE

Welcome to the FORUM. 12v voltmeter should be OK (I have one done that way) Resistor depends on whether you install a 12v coil with internal resistor. If you keep the old 6v coil, install the resistor between the power source and coil. If you change to a 12v coil w/o the internal resistor, install the external resistor between the 12v coil and the points to keep from burning them. There's quite a bit of info on the CUB FORUM and probably in the HOW TO forum, check the INDEX PAGE and/or use the search feature, top right corner of the page.
