re

That to me indicates a wiring problem. 'the switch' is 'the thing' that
should control whether the light is off or on.
If it's on all the time..........
I'd access the other end of the wires at the control/knob panel. See what I
could fine there.
you are aware of this factor , right ? :
if you are going straight when you go to engage the rear diff lock..........
if things don't 'line up' right ..........in the one of I think, 6
positions............it won't lock,
*until* there is some speed difference between the rear
wheels...........either from one slipping more than the other on a slippery
surface, or you weave or turn to cause that to happen.
I always wanted to make some other deal to operate that shaft.
there is a expensive custom made upgrade for that diff locking actuator
shaft, pretty sure.
