Allis Chalmers Wd 12 Volt Wiring Diagram

Aaronyoder, I read the postings of others on here, They have good suggestions. I redid my WD45 to 12 volts many years ago. the tractor had decent wiring and I put on the older style alternator with external regulator. I ran a wire up to the regulator from the key switch and that worked out great, no resistors or diodes..

(quoted from post at 20:23:01 09/16/08) your regulator should have 4 terminals. on the bottom is the 4th. The B is battery. it goes to the amp meter, out of the amp to the battery. the F is field- goes to the generator F. the G is generator, goes to the A terminal on gen. the L is load or light. it gest voltage from the light switch on the first generation regulators. try leaving it blank.
