Combines M2 Battery voltage light

[tbran]

The first thing to check is the cab main ground. Remove the bolt and sand and reinstall, make sue the cab ground to the combine is good likewise if problem persist the master solenoid as a co- second choice. This can be checked by jumping the two big posts and running to see if this solves problem. IF not the master breaker back on the engine is the cuprit. This assumes the battery cables are OK.

I had the exact thing happen on my M2 I couldn't track down the problem I checked or replaced just about everything (door relay, main breaker, cab ground, fuses etc.) in my case it turned out to be the crimp on ring connector on the starter post that takes power over to the main breaker on the motor, a quick squeeze with a vice grips and everything has been good since. Sure gave me fits at the time. Good luck.
