Ground drive solenoid Defective

Hey everyone I’m new here, just wondering if anyone’s ever had the code Ground drive reverse/forward Solenoid defective on a 760 or something similar. Started the combine once and blew the 15 Amp ignition fuse before any screens turned on, replaced it and it fired up and gave me the code. Shut the combine off, turned off the master switch and turned it on again and combine started and drove with no codes. Now it’s just blowing the fuses as soon as the engine cranks for a second. We can get it started the odd time and just throws the same code and we can’t move the combine. Prior to this problem once or twice a day I would get a code “Wrong transmission configuration”, and it would come on and off multiple times within a second, anyone dealt with anything like this before?

Check the wiring harness on top of the transmission. Sounds like you might have smoldered some wires

We had looked on top of the transmission for something out of place for hours and only thing we found was a plastic wire shroud a bit squished. Had a Class mechanic out to investigate said it was a short in the main wiring harness on the right hand side of the machine, he unplugged a jumper for the emergency steering circuit or so it’s called? Didn’t make sense but also had something to do with a hydraulic pressure release solenoid that activates when starting the engine to make it crank easier. So we essentially disabled that “feature” and combine still starts perfectly fine and no code. So I guess we’ll inspect the wiring harness this winter to see if we can find the short. That’s a big expensive and complicated wiring harness the replace
