Combines Voltage problem with R42

[Gleamer]

I had the same issue, new alternator etc, I had a bad electric motor on my air conditioner fans. Basicly I had a short to ground. Chase your wiring harness for any switched wires that are use for the harvest mode. You may have a chaffed wire touching ground somewhere. Good luck

I bought an inexpensive amp tester, and tested blower wires and found no problems. Replaced 2 breakers on back right side of combine, still didn't solve problem. Finally hot wired around relay in cab and worked fine. New relay solved problem. Good luck Steve

If the other suggestions don't work I'd suggest doing a load test on the individual batteries; maybe one of the batteries is bad and may mess with the rest of the electrical system if the battery has an internal short.

I had a bad connection on a wire coming out of the fuse panel in the cab. I replaced a few wire connectors and eliminated the problem.

Replaced the console relay and it fixed the problem. Just kind of wonder what made it go bad. Thanks to everyone for your replies. This website really is GREAT.........
