Today I drove my 25 Indiana to town, about 9 miles on the back roads. We stopped for Ice cream and everything was great. When it was time to go home the truck wouldn't start. I checked everything like gas to carb and switch on ect. but when I checked for spark we had nothing. I then pulled the cover off and filed the points on the mag. and still nothing. After working on it till almost dark I gave up and called for help to get me home so I could bring the trailer back. After getting the trailer to town I decided to try it one more time just for grins and the truck started right up so I drove it into the trailer and shut it off. I then started it again and moved it over a little and everything worked fine. Now I am lost as to what was wrong before. The truck runs on an Eisemann Mag. and the only wire other than plug wires is to the kill switch which is nothing but a ground. I even took the wire off and tried to start it in case it was grounded out someplace and still nothing. Now that it runs again I don't know what caused it to stop and don't want to get stuck again later. Anyone have any idea of what I should look for?

Bob

You might check for a broken wire inside of the insulation somewhere Bob. I've had it happen on more modern stuff before. Dave

The thing is if the wire was broken it would still throw a spark. The wire is not needed other than to kill the engine after it is running. That is why I took the wire off and tried it again with no luck at the time.

Sounds like an electrical component is failing when heated up.
Starts working when it cools down.
Is there a condenser in that mag?
Maybe the coil in the mag.
Some other piece?

I was thinking the same thing. Coil or condenser failing. Or both. Unfortunately it might be time for an expert to look it over.

Check the switch itself. If you turned it off and on a couple of times perhaps you corrected the contact problem. Maybe the back road was bumpy enough and caused the switch to come apart at the contacts.

Is there a wire inside the mag going from the coils to a kill switch terminal that an external kill switch wire attaches to? If so, maybe there is an intermittent short on the kill switch circuit, but inside the mag.
