Truck was running fine stopped at a job would not crank ,no power windows wipers all else seems ok. checked fuses and wiring under dash. only way to start was to jump solenoid
First thing to check for is if the starter has a thermal overcrank or not, thermal overcrank sensor is located right on the starter it should have two wires going to the connector, check to make sure you have a ground to one wire at key engine off, next if ground is present on one wire plug back into sensor on starter and make sure ground is bridge or present on other wire, if ground is not transfer to other circuit when plugged in then thermal overcrank sensor is bad than just jump circuit or replace sensor, now if ground is not present on either circuit at key on engine off than applied ground to both wire and retest starter cranking at key switch, please update once test is complete, thanks.
If it a standard check the cluch safety switch, i had a switch come apart on a f250 before and caused this
