Locker engaged but indicator light stays blinking

I put the rear axle of the truck on jack stands yesterday and confirmed the rear diff was open when the locker was off, and engaged after the locker button was pushed. The indicator light for the locker continues to blink even when the locker was engaged. Any ideas?

 

Were you in 4WD?

 

Yes, 4Lo.

 

Sorry for the stupid question, just wanted to check! I wish I could be more help, but I don't think I have ever engaged my rear locker. It's a pretty stressful thing for the drive train, maybe the light is supposed to blink to continuously remind you that it's engaged. Have you referred to the owners manual to see what it says about using the locker?

 

The truck almost always needs to drive forward and sometimes slight steering input is needed (to get the rear axles to turn at different speeds) to fully engage.
Have you tried while driving? Why are you attempting this on jack stands?

 

Testing it on jack stands to verify the locker engage. Forward, backward, slight turn right/left forward/backward, tight turn right/left forward/backward - indicator light still blinks. I can hear the locker engage from the rear tire slip on gravel while turning, indicator light is just out of sync with the state of the locker.

 

The locker needs resistance to engage and be in 4 “low . It usually takes a few tries for mine to engage .

 

Can you explain in more detail how you determined the locker is engaged?
