Manually engaged dif ock. or an electric switch on the dash? Switch s the normal set up, meaning there is an electric solenoid used to engage the differential lock.

If solenoid gets voltage, the solenoid may have failed.

That is how I check the loaders at any rate.

this is what I could locate so foar on schematic 4601 being the lock solenoid and the location
