Now the e locker kicks out over 20mph, so if play off road in muddy or snowy conditions we just have to keep the speedo under 20mph 
I know I've hit a lot more than 20mph in mud pits and snow drifts not to mention slippery hills.
I still want my elocker to stay on when I turn it on.

Re: Rear E-Locker
I made the mistake of not getting the off-road package so I can't just try this on mine. How about this. With the key off, disconnect the connector from the e-locker. Measure the resistance from the black wire (going to the control not to the e-lock coil) to a good ground as close to the control as possible. Zero out the probe resistance first.

Re: Rear E-Locker
I have the service manual and pages 4-150, 4-156, 4-160 explain the following respectively: Differential lock schematics, Circuit Description, and Electronic Diff Lock Will Not Disengage troubleshooting. I wish I could post this and have it be readable or be able to explain it. (I'm a Pharmacist not an Electrical Engineer)  if anyone else can post this info for ChevyHighPerformance to look at we might have an answer.

I have these too. The control monitors the return. My question is it through a relatively large resistance to limit current (like 3 ohms) or a small resistance (like 0.25 ohms) just to monitor the current. My guess is that it's a small resistance, but I'd like to make sure. That's why I asked for a resistance measurement. |
