This is what I used on an Oliver, no problems at all. You can get the diode at Radio Shack real cheap 4 for 5bucks or something like that.

Thanks Dave, I have the "idiot light" in line, and will have to double check all my wire routings. I may map them out and post for some second eyes to take a look.

Thanks for all the help so far, the diagram helps a lot.

Here's another one, Bob Melvilles wiring diagrams. This is what I used when I rewired my COOP E3. I put a generator from a JD M on it and used a regulator instead of the generator cutout that came on it. On an Oliver 88 I put an alternator on it using Bob's diagrams. Both situations worked great. On the E3 you can see where I mounted the VR on the bell housing. By putting a shorter belt on the Oliver alternator it fit under the side panels. Never had to rev the engine to start the alternator charging either. If you want a diode email me with your address. I no longer do full size tractors, no room.

Find the problem and leave the gen light on there.
Not only is the light an alert to tell you if the alternator is wirking or that you have forgotten the ignition turned on, but the idiot light can make for easier starting.

Using a gen light to excite the alternator only adds 1/4 amp load on the ignition circuit to excite the alternator, while using a diode adds 2-3 amps load to excite the alt. This nearly doubles the load on the ign switch and wiring, which can cause voltage drop and weaker spark.
