Massey 3065 electrics

[Adge]

Evening all, is anyone able to help?
I have a 1994 3065 with many electrical issues to solve! Would anyone have a diagram for the cab harness for this particular year as the one in the workshop manual is for before this and illustrates a previous autotronic box than I have. Thanks.

You don't say what sort of problems you're suffering from, but before anything else check that the alternator is putting out 12v+. As the voltage drops below say 10v it gradually causes more problems.

Basically a previous owner has at some point bypassed the autotronic box. All the controls that should run through the box are now on separate feeds and run direct to the relevant solenoid, everything works but the way it’s been done means it doesn’t relate to what’s displayed on the dash and I want to put it all back to how it should be but only have part of the original harness to work from.

You might put it back to original state and find out it works better modified.

No doubt it will, would have been modified for a reason but I will put it back as it should be to find the original problem and than sort that too

I had a 3065 that used to play up occasionally pto drop out, low back end pressure, default to 4wd. Turned out the connections inside the black box under the offside step had worked loose, I think it is quite common on the original Autotronic tractors

Update.. after a few hours of head scratching and wire chasing I’ve now got everything working as it should apart from the lift arms! Both lights on the ELCU stay on?!?
