Best thinking I have: If a cutout relay will not disengage (open) it is not working correctly. If the Cutout is a 6volt (it could happen!) it might remain closed dispite the reverse current flowing through it. If it has solid state diodes in the regulator circuit, the regulator must be for the correct polarity of ground. (most IH 12v generator systems were pos ground.) Those two things could be the cause. If not the spring that is pulled to make the cutout open (it also resists the closing) could be adjusted for earlier opening and harder closing of the cutout points. Just a little at a time. With the tractor off, and cover off of the regulator, the cutout movable contact can be pushed closed by hand. If it sticks down, (it has been) the spring is too weak. (use a popsickle stick or plastic knife and open it to avoid smoke. Tighten the spring (it might mean bending a metal tab, or a screw.) (do this with the bat cable removed to avoid more smoke) Very little adjustment is needed for each attept. When it finally reopens on its own when released, it is time to try it with the cover on, and the tractor started. (be prepared to remove the cable if when shut off it continues to draw as before) It might take higher RPM to start charging, that would be a function of that extra spring tension.
If this is still not operational, or you want a simpler answer, put a used diode (pulled from a full sized GM car alternator. Use a diode that stops flow to the gen, but allows it to flow to the cutout. (1/2 the diodes are polarized one way the other half are the other way. If the body of the diode is kept from grounding, either will work. Best of luck, Jim

Today's Featured Article - Maintaining Rubber Tires - by Staff. The broad use of rubber tires on farm tractors and machinery has resulted in a great saving in both time and operating costs since the time of steel wheels. There are, however, certain basic fundamentals in the care of tires that should be followed carefully if the owner is to derive maximum benefit from his or her investment. First and most important is to maintain proper pressure for the work at hand. Your best guide to proper inflation is the operator's manual or instruction book tha
