Intermittent Locker Indicator Flashing

So since I got my 5.29s installed I have gotten an intermittent flashing locker indicator light when I first start the truck. It happens every one in 10 or so starts and goes away as soon as the truck starts moving. Whatever the issue is does not seem to have any effect on the function of the locker, rear diff, or truck. There are no odd noises or anything else that would indicate that this issue is anything other than electrical.

The shop who did the gears already pulled the diff back out to see if anything appeared “off” and replaced the blue connector for the locker for good measure. They are going to be looking into this further but I figured someone here might have dealt with a similar issue.

Anyone have any thoughts?

 

Anyone have any ideas? @Texoma shared this in the 5.29 thread:

Seems like the most likely cause at this point, but trying to get as much info as I can so they only need to have my diff apart one more time to get this done!

 

Keep us posted please! Sounds like an annoying issue. Other than light flash— any other issues?

 

Very annoying but its only at start up and causes no other issues at all. When I'm in 4L and have the locker engaged, it stays properly engaged. I'll definitely keep you all posted.

 

Yeah, they did NOT replace that connector when they did the initial install, but they did replace it yesterday in the hopes that it would fix this issue. It did not unfortunately so it's back to the drawing board.

 

You can remove the screw for the locker indicator and if you can pull it out, it's in there wrong. You have to install the indicator before you install the carrier, and even then it has to be positioned right.

 

Sounds like no matter what the issue/fix is, the carrier is going to have to come out again.

 

Yes
