    Posted: 22 Sep 2011 at 9:53pm
I just bought an allis chalmers b, and it is a wire mess. It has been converted to twelve volt, with a 6 volt coil and a stabaliizer. The wires for the lights are hanging all over the place, the timing is off, and the off/on switch is busted. Any advice or diagrams would be nice, Thanks!

Maybe tear all the wires out and start over or decide if you want to keep it 12 volt or not. I guess I never believed in a charging system much on tractors, they start almost instantly. Most of mine that get used all the time have no charging system at all and go 2-3 years before they need a charge, they don't have lights either.

Seems like you need to talk to Steve at B&B. He is usually on the Farm Equipment section of this forum.

If you need a new wiring harness, contact Steve at B&B.  He is one of the advertisers on this site, and is VERY Helpful whether you choose to purchase his product or not.

There is not really to much to wire a B.
I never found the need to buy a harness.
Just some wire and some split poly wire loom from NAPA.

If it is converted to 12 volt, you might have an alternator. You dont need the resistor head light switch since the old 6 volt generator needed that for current control. You still ahve the 6 volt coil, so you will need a dropping resistor to get the 12 v battery voltage down to 6 v for the coil.

Would it be cheaper to buy a 6 volt alternator and 6 volt points, or to just go ahead and buy a new 12 volt alternator (mines busted) and the 12 volt coil. I want it to either be 6 or 12 volt, but this half and half stuff is bothering me, especially since it doesn't work.

I would get a 12 volt alternator with a 12 volt coil that does not need the resistor. Points are the same for both 6 and 12 volts.
