Great question. Probably not. I will assume the following: The battery is in with positive ground The regulators you have tried are either non polar (good for either pos or neg ground), or says Pos ground on the underside. That the "red" wire (above) is from the load side of the amp meter. That the regulators are for regulator grounded field(A)type charging system. Not "B" type with field supplied with regulator voltage. (Ford type)
If the above is OK, the regulators (all three) are faulty, or connected incorrectly. the regulator has two separate components inside. a cutout relay that prevents the gen from sucking current from the battery when it is not turning fast enough to charge the battery, (or spinning at all) This consists of a set of contacts that are normally open. They connect the BAT terminal of the reg to the ARM terminal of the reg, when closed, and break the connection when open. The contacts are closed by a winding that senses the gen output voltage, as the gen spins up it produces output from residual magnetism in the iron field poles(not electric current in the field) this voltage pulls in the contacts and starts charging the battery. If the tractor is idled down, the gen will not produce enough voltage to charge. As current begins to flow backward to the gen windings, a second set of coils in that cutout counter the first, and the cutout opens (usually at about 2 amp discharge backwards.) Thus if you measure the electrical resistance from the Bat terminal to the Gen terminal with the regulator in your hand disconnected, it should be infinite (open) that should also be true from the Bat terminal to ground (frame of the regulator), but not from the Gen terminal to reg frame. If there is conduction from Bat to Gen in your hand, the contacts are welded together/stuck or broken. Pull off the cover and look it will be the relay with the big contacts. Let us know in a new posting. JimN

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
