Starter issues ~ Ford F 1300

[Wakey]

Here is the original thread where I asked for help identifying which starter to purchase for this tractor. http://www.tractorbynet.com/forums/ford-vintage-tractors/315179-need-model-ford-f-1300-a.html

The new starter only lasted 1 week!

I can't blame the new starter because it did the same thing the previous one did which was basically almost catch fire while the tractor was running.

I "thought" I found the source of the short but apparently not.

Perhaps the key switch still sends the positive leg to the starter after it should be stopping. I traced the wire from switch to starter and it looks good. I taped up all the wires that had nicks from long ago troubleshooting.

The key switch was replaced right before the last starter cooked so that must be the problem. I tested it with the volt meter and it seems to act normally. When you turn to start it sends voltage and when you release, the voltage drops out.

I suppose I can put some graphite in the key switch in case it might be sticking causing the starter to turn while the tractor is running.

Am I missing anything? Should I put a big red LED that glows when the starter is getting juice from the switch leg?

Also, my guys said sometimes one of the white lights on the dash flashes?

Thanks in advance for any advice!

I sure would route your ignition switch to starter wire to where it is more protected, and perhaps put some wire loom around it. It must be contacting a 12 volt source somewhere and it is chafed? That's the only thing I can think of that would keep the starter engaged other than the switch itself.

Good luck!
