Hello All
1996 Factory locked FZJ80
My rear diff lock has gone into retirement and I’m trying to bring it back.
Front and center diffs both lock without issue. The dash light just blinks for the rear, and the diff does nothing. Both rear wheels off the ground at the same time … they spin freely, in opppsite directions.
Before opening it up, I want to rule out electrical options. I checked the fuse, it appears to be good.
Based on wiring diagrams, I checked for power, and even tried using a jumper, but had no success. But truth be told, I’m not sure the right procedure for this step. I’ve heard something about a 9V battery test, but don’t know what that’s about.
I have a volt meter and usually know how to use it if I know where to tap the probes.
With the ignition on and switch on, I checked for 12V power and found nothing on the GL, G, GB, and GY wires. Is this the correct spot to test? Would jumping 12V power to one of these activate a locker that is working properly?
Thanks for any help or tips!
