Ignition Key Short

Doug (OH) · Nov 8, 2010

Hi all, I rewired my '55 Ford 640 during the summer. The tractor was previously wired for an automobile style switch, bypassing the push button by the shifter and it has been converted to 12V. It snowed. Tractor got wet. I put in a freshly charged battery (which I was charging up for winter anyway) and the darn thing cranked slow, then I notice smoke coming out of the hood.At least three of the wires at the switch were having a melt down.(I did not skimp on wire guage when I rewired.) I have a newer solenoid with the push button on it. Used that instead with the ignition key on. Cranked great and started. Any ideas where the short is coming from? Thanks, you guys always give great advice!

poor contact either by not maybe having connectors tight or corroded. could cause heating of the wire melting insulation.

All it takes is a little dirt or rust or water to make things go bad fast and then smoke things. Double check all connections and make sure all is tight. Oh by the way them universal ignition switches your luck if one out of 10 are any good now days
