I just got done working on my E-locker 3rd replacing trashed bearings, see pic. After everything was put back I couldn’t get the locker to work, and of course I forgot to test before working on it. The only issue I had working on the 3rd was forgetting to lock it before removal, had to jump it manually on the bench before getting the 3rd back in.

Things I have tried:
Removed the actuator and bench tested using a heater relay, actuator ran perfect. Free-lock and back
Plugged in uninstalled actuator and could not get any movement.
Disassembled actuator to test connector to limit contacts on plastic gear it checked out fine.
Tested resistance at 4WD(diff) ECU between motor leads and got <100 ohm.
Wire jumped diff lock sensor connector to fake a locked state, red rr locked stayed solid.

Have the truck set to ignition on, L4, N and 4wd button off. Also tried with 4wd button on not sure on where that needs to be.

All I get is the flashing rr lock diff light with no movement from the uninstalled actuator.

Any advice?
