Apes rewired my TO-30

Wild ones, with absolutely no regard for nice safe wiring.

Tractor was like this when I got it. I was planning on eventually getting an OEM style switch to replace the push/pull ignition control it has now and redoing the wires but something came loose and killed my ignition.

Not sure what the thing in the middle of the pic is. Is that a ballast resistor? I thought maybe a 12v to 6v voltage reducer but it has 12+ on each side according to my voltmeter so I'm guessing ballast resistor. Wires on one side go to the coil, the other side has 2 wires, one goes to the ignition switch, the other goes around to the other side of the engine and is hanging loose, the only thing I see it could have gone to is the alternator so I'm guessing that's where it went but I really don't know.

I can start the tractor and have it run by running a jumper wire from the battery + terminal to the ignition switch side of that doodad in the picture.
I've got a wiring diagram of sorts but it's for a + ground 6v system which if my tractor ever had, it doesn't now. [/img]

That's what I'm about to do with my TO-35. The wiring that is there is old, and patched in ugly ways... Just placed an order yesterday with Agri-Services for a new harness. Got to place my order to YT soon for a Pertronix coil and ignititor, regulator, plugs and wires.. Figure just start it all from scratch and know what I've got.

Think my regulator and coil are fine as is, but I have a feeling I'm never getting all the terminal posts freed up, so for a few extra bucks, I'm saving that hassle.

Ok, so it appears my field wire wasn't even needed. Does fine without it. Strange.

L.O.L. I'v seen worse,mine was allmost that bad and still not right. I thought i would just rip it all out and start over with new guages and all. That just might be my spring time job,right now i need to get it ready to remove winter snow with. :)

Quoting Removed, click Modern View to see

Hmm could have sworn I got 12vdc on both sides of it. Could it be broken or installed backwards?

Also will 12v burn out the 6v ignition.... If that's what I have?

Unable to install backwards to the best of my knowledge. Might be no good. I suppose your machine does not run. Also that resistor won"t work until you put a load on it. Voltage is potenetial. That 6V voltage drop is only going to work when the current is flowing. So, if it"s just sitting there with nothing working, you will see 12V on both sides. if it"s running, it will show 6V on the back side.

The contraption in the middle is a voltage reducer. From 12V to 6V. Good for hooking up your OOGAH horn to 12V.

Ok I see no doodad between the switch and coil in any wiring diagrams so I'm gonna just eliminate it and see what happens.

Go to and look for a wiring diagram there. Your tractor has really been "farmerized".

If Apes rewired your TO-30, would you call that Monkey Business ?

I would have started to make myself a new wiring system, and got a new ign. switch.
From the pictures I think I would have been rather quick to disconnect the battery. Also that starter wire, the thick one, buy a little piece of shrinkable hose and shrink on the end, unless you get a new wire.

My dad"s old TEA 20 got on fire because of a spark and a small gasleak.
