Im trying to figure out why the diif lock is not working on this unit I rebuilt the trans, diff, and tandems about a year ago and it just started not locking ive replaced the valve, coil, switch, wiring, and pulled both tandems off checked pressures and still not locking any ideas before i tear the unit apart
So it was locking correctly after you did the rebuild 12 months ago but now it refuses to lock..? Did the problem start suddenly or was it acting up for a while before it finally quit..?
The problem started suddenly. Yesterday I went back through the wiring and found a wire burned in half so that fixed it it was in a spot that was almost impossible to see
Like when you lose something - it's always the last place you look when you finally come across it ........ Good to hear you got it fixed.
