I recently purchased a McCormick Farmall 100 Hi-Clear and I'm having trouble determining the age of the tractor. The serial number says 12673 J on the plate. Also how would I go about replacing the 6 volt system to 12 volt to eliminate the resistor.

Champ,
I simply Googled with "Farmall Serial Numbers", You might also Google "Farmall 12volt conversion."

Sorry, I hit the Post button before I meant to. /forums/images/graemlins/blush.gif Welcome to TBN. Don't forget to post some photos se we can get <font color="green">green with envy!</font>

With that SN it would appear to be an early 56 unit.

As for converting 6v to 12v to eliminate a resistor??? Be a tad more specific. generally, the 6v units dind't need a resistor inline with the coil, like the early fords did, but instead just used a 6v coil. Now if you went to 12v and kept the 6v coil, then you needed to add a dropping resistor, or simply use a real 12v coil.

The only other place i can think of a resistor being is in a lamp dimmer switch or a 'tickler' switch incorporated into the lamp switch, or main rotary knob to control generator output. The tickler portion of a switch made to further excite the genny field will probably be rendered useless depending on how you achieve 12v. most just hang an alternator .. 3 wire job, or 1 wire job.. etc.

Be a tad more specific about what you want to do. I have worked on plenty of these old tractors, including IH.. they have pretty interesting ignition systems, in some cases, with ignition power drawn off a tap on the VR.. etc. If I can be of assistance.. just hollar!
