Where does the other end of the wire conect to? The ignition switch? Or the coil?
Ok the wire to the points and condenser should come from the coil not the ignition switch. The wire from the ignition switch goes to the other terminal of the coil.
Basicly when you plug the wire from the ignition switch into the points you are causing a direct short to ground.

Smitty ~ Why has this engine run for 37 years with the wire connected from the switch to the condenser? One of the coil wires under the flywheel runs to the condenser terminal with the wire from the switch and jumpers from there to the points by a 'y' connector. The other coil wire is connected to ground on the stator which is attached to the engine and is stationary and a ground.
Ah ok you have a bassakward ignition system. It uses the positive for a ground and the ground for the positive. Many older diesel trucks used this type of stystem. I almost smoked a guys whole electrical system once due to this set up.
Check that you have the battery set up the same way. You may have installed the wires like a normal automotive set up. This would again cause a direct short to ground.
Smithy ~ The battery connection is and has always been Negative to Ground. I also ran into your same situation on an old International truck and blew up a battery when trying to jumper with cables. Whew!!! I don't feel you have answered my question or helped me solve my problem. There has to be a short in the stator winding? or something else. I didn't want to take it to John Deere and pay $500 bucks or more to get it fixed.
Ok You say that the wire going to the points comes directly from the positive wire of the battery (through the ignition switch) without going through the coil. And that the negitive side of the battery goes to ground.
Please look at the following diagram of a 12 volt ignition system and tell me how that can work, please.
I must be missing something here.
