Thread: Diff Lock Light comes on when not locked

I have checked, and the diff actually doesnt lock when this happens, so it must be electrical.

My question is: is this a common problem? I will investigate the wires and switch, but has someone else had this problem?

not super common but Ive changed a couple of switches because of it.

its most likely a gradual build up of oil in the switch causing it to short and occasionally Its been enough contamination and oil on top shorting the pins to earth.

Sounds very probable. Thanks mate.

^^^ yep, quite common, BUT, don't replace the switch, it can be carefully pryed apart and cleaned out, then put back together with a smear of goo and refold and it will last another 20 years

Since the switches I replace dont cost me anything........


Lazy...
