Toyota 80 Series Factory Diff Locks

[hippy_]

I have just started to get these going. Currently I have cleaned and rebuild the rear diff lock. I had the truck on the hoist and had the diff lock engaging/disengaging, take the truck off the hoist, with the diff lock off. I them drove the truck back and forward in the workshop with the diff lock on, it was engaging going forward and would disengaging when going backwards??? Is that odd?? Then I drive home and try it again....... This time its stop engaging at all??? I cant work it out??

Any ideas??

check all the cabling sounds like a fracture in the cable of fittings do a contineuity test whilst moving and wiggling the cable around

Will have a look around when it goes back on the hoist on Monday...
