Front Eaton E locker problems.

[rascole]

After I installed the rebuilt front drive shaft and al 4 corners were up on jacks I slow rolled the drivetrain to listen for unusual sounds. Wanting to check the lockers I engaged rear with no problems. After engaging the front the wheels would not lock, after verifying polarity, voltage and shifting through gears, high low nothing changed. Then the smoke started. Has anyone seen a Eaton E locker fail like this? I am using a sPod and ran several different circuits from the same set of posts and amperage was consistent for each loop. Ohm reading was .4

Crispy! Sorry, that's all the help I can offer

I can measure the ohms on mine when I get home, but that looks like an overcurrent where it drew enough amps to melt the insulation but not enough to trip the fuse or breaker on the sPod.

I had a little time to work on it last night and the wires going into the rubber grommet are fried too. Plan on hitting Big Bear this weekend so it will wait until this summer.

That’s bizarre, curious if there was an internal short

Pretty sure it is a short on the coil. I have seen it on many solenoids and these look to be similar in design. I think this is the one you had back in the day so it has some miles on it. This just may be a sign that the OD Dana 50 is next.

Maybe zip tying it to the exhaust manifold wasn't a good idea . . .

Ive had this happen on a elocker due to bad coil and also seen it on two junkyard Elockers as well. One of the many reasons we went with a air locker when we did the swap

So, about that swap????????

Checked in at the shop Tuesday. Housings were in stock ready to be machined and we were told we were next in line for our run. They were wrapping up a huge order for another client

Got the front diff on the bench today and pulled the cover off. Wire was broke and insulation was toast. This is the first time I have seen the Eaton locker but from what I see I don't think the locker is supposed to have these chips in it. Anyone have input?

Just went and checked mine, those are just casting marks. Hard to tell straight on from the side, but looking at it from an angle you can tell.

Here's some pictures of the casting and what the wires should look like. This is a fully working locker. Replaced it with an ARB to match the rear. Really should put these up for sale.

Got the front diff back last night and the shop said I was lucky. Old coil work fine, he said the must have been just enough wire hanging inside the diff to cause it to eventually wear and short out. Added new wires and it's good a
