Go to a library and look up delco type A generators in either tractor, or auto books from the 50s. (common as fenceposts) you will note that the system is not overly complex as a diagram, it is just the reality of the actual parts that seem inscrutable. If it will not charge with the field grounded, it may not be getting the cutout relay to close. There is a pull in winding on the cutout relay that senses voltage from residual magnetism in the field and connects the armature with the battery. This process starts the generator. If the regulator is not grounded to the tractor frame/engine/generator, it will not pull in the cutout relay. To see if this is the case, disconnect the A terminal from the gen, then use a jumper wire from the battery neg terminal to then just touch the armature terminal for a half second. There should be a spark (pretty healthy, but not a direct short) this spark tells you that the armature is able to conduct current through the windings to internal ground. (probably good output components in the gen) Next disconnect the F terminal from the Gen and use a ohm meter to see if it conducts from the F terminal to the third brush. If it does, (no resistance <1ohm) the field circuit is probably OK. and the regulator (or its ground) is the problem. Note of importance Farmers were often functionally able to do these types of repairs as a part of operating and Keeping their stuff functional. There is no reason you cannot. It is one component of the hobby that many of us treasure. Please do not despare. JimN

The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
