Diff Lock Light

<< < (3/3)

AbyssDJ:
our light stays on all the time regardless - the switch is stuck. although its off at the moment, because the cable came off when i was underneath it doing something or other! diff lock works fine though

SteveG:
I understand the principle between turning radii and the rotational difference between the inside wheel and the outside wheel when turning, the point about posting was to check what diff lock this was a test for as in my opinion it's not a guranteed test of a centre diff lock as you have open diffs on each axle.

If I'm right another way of testing diff lock is if you put the vehicle in neutral, jack up a wheel on each axle with the others on wheel chocks :wink:  and then turning one of the wheels in the air, the other wheel in the air will move at the same rate.

Cheers

Steve

--- Quote from: "markyb" ---my diff lock light has a mind of its own comes on sometimes flickers and stays on .

so are you talking centre diff not working or just the light

There are numerous things that can go wrong on your diff lock. Either the lock engages or not or the light says it's engaged or not when it is or it's not! Glad I made that clear  :lol:  :lol:

First thing to do is to see if diff lock is engaging. As mentioned above there are a few ways to do it ranging from driving in a tight circle to removing a prop shaft. Up to you how you find out. If it's engaging and the light isn't on the most obvious cause is the bulb has gone but it could be the switch on the box. If it's not engaging but the light says it is, it could be the switch or perhaps a short somewhere.
