REWIRING TO 12 VOLTS

Glen Higgins · Mar 12, 2012

Thanks to old,steve & ted for their replies. I have a allis chalmer B. When I bought the tractor it had a one wire alternator and 12 volt battery. The battery was bad had to replace. I used it for about 2 to 3 mos. Then I had to charge the battery. When it comes to tractors ignition and etc. I am not good at it. Make a long story short I replaced the alternator with one wire. When I did this I found the alternator wire was hooked up to nothing. The orginal switches were removed. There is a toggle switch one wire coming from pos. side of battery the other coming from switch goes to coil-not sure. It was suggestied that I run #12 wire from alternator to ammeter from ammeter to starter. When I tried to start it would't fire. HELP Glem Ga.
P.S. I haven't tried to start it today because I want to be sure I have the toggle switch wired correctly. Thanks

Search the topic on this forum several diagrams are posted. Your explainatin is not clear enough to help us help you. Do you have a magneto or has it been converted to a distributor? Get a friend who knows what he is doing to help you. You can get a lot of help here but your terminology and descriptions have to be correct otherwise we are guessing at what you mean.

You didn't wire that mag into the battery system did you????? If you did then you stand a very good chance you let the smoke out of the mag and yep it will not run. With a 1 wire alternator you have no need for a switch in the charging system since when the alternator spins up to X RPM it will start to charge.

It might help if we could see a picture of your mag. Some times, the coil went bad in a mag and people wired in an external coil. If it has an original mag, it should not be connected to the charging circuit but may have a grounding switch in the electrical box to kill the engine.

No. I sent you one today. Tried to PM you but it was down.
