The contacts you are touching are the cutout relay set in the VR. If the generator is a three brush style, move the third brush all the way as close as possible to the fixed brush on that side. This will boost charge to get the relay to latch. If it is not a 3 brush, try this. With the tractor at 3/4 throttle, and all wires connected, ground the F terminal on the generator with a jumper. If it now latches, the VR voltage relay might have dirty contacts. The VR will not act correctly if the cover is off because it has an effect on the magnetism in the unit. Be sure to check operation only with the cover on. If it still will not latch, and the generator puts out well when working I would reduce the spring pressure on the contacts you are pushing on. (this is not easy, it is touchy, and is responsible for opening those very contacts when the engine is idling, or stopped. Be sure the contacts open when the tractor is shut off or it will smoke the generator, and discharge the battery. Adjust just tiny increments. Jim
