Some have trouble reading them. If you are inexperienced, but know you have a Ford 8N front mount distributor tractor and want to convert it to a 12v system. This sketch may help you. If you are technically savvy, you don’t need this sketch. This sketch illustrates a basic wiring conversion for a specific tractor and in no way covers all situations and goals. Just go ahead and rewire the whole tractor! Sometime starting over is better than trying to figure out how someone else wired it. Good Luck! [Reply]   [No Email]

You don't have to over rev the cold engine to get that one wire to start charging if you have another wire to one of the small spade connectors on the alternatore and use either a press to engage switch on it after the engine is running or a diode in that exciter wire or even a small clearance or instrument light in that same circuit to excite the alternator upon turning on the ignition switch to which that wire would be connected if usine any of the two last mentioned citcuits.

Even the better 3 wire set up is so easy a child can do it. Bob has posted a picture for years how to do it and the archives are full of them. Just had it posted in the Farmall forum today [Reply]  [No Email]

At least you did include the MANDATORY "infamous ballast resistor" required for the modern 12V squarecan coil ........Dell, a 12V advocate for the right reasons, who knows 8-ways to convert to 12V and they all work the fist time [Reply]  [No Email]

Dell, You've been repeating this for years and I'm still wondering why you gotta rev your cold engine. If there's enough juice in the battery to start the engine there surely is enough to let it idle for a few minutes and warm up before you rev it. Yes, I understand the advantages to the 3 wire. I just don't know why you gotta rev it cold. [Reply]  [No Email]

So iff'n you don't "juice" yer engine, you will DISCHARGE yer 12V battery and NEVER charge it. Ittza built-in voltage regulator scheme. Once you "juice" yer 1-wire alternator, it will charge at 600-rpms just like the 3-wire alternator with idiot lite. ........Dell, 12V advocate for right reasons [Reply]  [No Email]

I have even seen some that have a sticker on them that says something like it takes 1800 RPM to excite [Reply]  [No Email]
