So, it's been a few months since I've used the locker and today I thought I'd give it a litte test and it failed! <img src="/forums/images/graemlins/frown.gif" alt="" /> I have ice on 1/2 of my driveway - so i parked with one side on the ice and others on concrete - and I was just spinning the 1 rear tire. So, I flipped the locker switch (not factory - it's retrofitted e-locker so I can and have engaged it in 2wd) and nothing - still just spun the 1 rear tire. I backed up drove forward in a little "s" to try to get it to lock but nada - just spun the 1 rear tire. I even went out to a dirt field were I've tested the locker before and it isn't engaging. As stated, it's a retrofit - so I don't have a little light on the dash to tell me it's locked on not.

I'm pretty sure it's not the wiring cause when I flip the switch on and off I can hear a click behind the dash and little 2 second humming at the differential. Even so, still doesn't lock up.

Any ideas what else might be going wrong? or what I can check.

Thanks,
John
