FORD 1920 WIRING HARNESS

[MARKSDAMFORD]

I HAVE A FORD 1920 4 X 4 WITH A ELECTRICAL PROBLEM. SOMETIMES IT STARTS SOMETIMES NOT. AFTER CHANGING THE IGNITION SWITCH, GROUND WIRES, AND CLEANING CONECTIONS, I HEARD THAT MY PROBLEM LIES WITH THE WIRING HARNESS? HELP!

Does it turn over and not start ??? or is there nothing when you turn the key ??? There is a neutral start switch , should be a clutch pedal switch or a problem with the PTO neutral switch..Just how can someone say for sure "It's the harness"?? Unless the harness is burnt to a crisp , It's repairable....

Theres nothing when I turn the key. If it is in the barn and there is moisture in the air it seems to not start. If I drag it out into the sun and it warms up a little it has no problem. There is no problem cranking or firing and that is what is so frustrating. I have been slowly tracing each wire and checking for bad spots hoping to stumble across it but no luck so far.
