Does anybody know where I can get a wiring diagram for a 1942 9n Ford with a cutout and a resister? I"ve got an IT Manual but its not very good! It covers 9n, 2n and 8n and is not real specific about any one. I"ve got a new amp. meter on it and a guy told me I can"t use it on a negative ground and that it must be like the original which is an inductive type rather than a 2 terminal setup??? Can anyone help?
