A couple of weeks ago, on a trail ride with some friends, I discovered my e-locker wasn't working. At home, I checked all the wiring for cuts, nicks, and pinched spots; and I confirmed that I had power to the connector at the right time and place. The motor was just dead, no clicking, no whining, nothing. After reading some on the ttora forum and pirate I decided to tear it apart myself. There was plenty of dirt and grit between the worm gear (on the armature) and the ring gear; enough so that I could not turn it by hand until I had it partially disassembled. I don't think anything is broken or needing to be replaced, just a simple clean and reassemble.

Now for the tech question. What should I use to clean the electronics inside the motor part? What kind of grease should I use to reassemble?
 
dielectric, small amounts.
 
Definitely dielectric grease on the electronics. Might even see if there's some way to seal it up a little better if possible...maybe some Ultra Black around the housing? If you need grease between moving parts, I like the water proof "Green Grease" since it has a very high operating temperature or regular old Aeroshell #17 like they use in winches.
 
Alrighty. Done a lot of cleaning and got it all back together (several times). Still nothing. I have confirmed power to the plug under the truck. I have checked the continuity of the five wires coming out of the actuator itself. We have bench tested with 1.5 volts, 3 volts, and 12 volts straight from a car battery. I have plugged it into the harness under the truck, and still not working. The only thing I can think of is that the little blue things in the last pic are capacitors and they are blown. The plot thickens. I guess I will try to convince my dad to take to an electric motor shop Monday while I'm at work.
 
I've got a used one laying around that may be in a little better shape. It has some corrosion I am sure, sometimes I would have to tap the housing lightly with a hammer to get the motor to turn. If you can't get yours working I will let it go cheap.
 
That's about what I went through with my locker motor when it went. After that point I figured I just needed to buy a new motor, witch I still haven't gotten around to doing.

I will say locking and unlocking it manually gets real old real quick.:handed:
 
Good news, the elocker is working and installed. After I purchase some vent tube tomorrow, it will be ready for the trails again. Bad news, I spent all day yesterday getting more and more frustrated at it when my ignorance was the problem all along. I had it fixed before 10am yesterday and just didn't know how to test it properly. The reason it didn't test good under the truck was due to a bad ground. Anyway, here is the best pic I have found that shows the proper way to bench test. I wouldn't recommend using 12v to test with unless you have the drive gear/back cover removed.

If your motor is giving you problems, I highly recommend you tear into it and fix it yourself. What do you have to lose? A motor that already doesn't work?
