Currently I have a M120 and having a bit of a issue with the display?
Tractor starts fine - every now any again the the display that highlights the gear selection along with the Neutral light goes blank. Doesn't happen all the time. Might work fine all day then the next day won't work for 2 hours. Shutting off the key my reset it - or may go blank again. Any suggestion? Thanks.

Sounds like a loose connection somewhere in the wiring going to the display. Could be power or ground. Would trace out the wiring going to it, and check the spades or pin connectors depending on how the harness is set up for bad or loose crimps and moisture or corrosion. Could be the display is going bad as well, but would save that for last.

I've spent 4 hours tracing everything with a multi tester. Got a copy of the service manual, there is a system diagnosis that is outlined in the manual. That's the next step - hopefully something shows up.
