<strong>Ok, here is what I think the locker ECU is doing. It sends out a 1 sec pulse to drive the electric motor. It will continue to send out this pulse until the RLP switch detects the diff being locked. This is why you see the light on the dash blinking. It is trying to send out the pulse to drive the electric motor until it locks. It only sends out a pulse to prevent the electric motor from jamming.

I wiried my locker up using relays on the limit switches. I apply continuous voltage to the motor until it reaches the limit switch. It always takes a little less than one second to reach the limit switch, and I can hear the motor running continuously during that time period. However, the locker usually won't lock/unlock immediatly, as indicated by the locked-indicator-switch. I usually have to roll a short distance for it to engage/disengage. I can usually hear a click when it engages, and a louder pop when it disengages.

Based on the above, I am under the impression that the actual locking mechanism is spring-loaded. The electric actuating mechanism simplyloads/unloads the fork that moves the splined sleeve in and out. Therefore, I do not understand the need to pulse the motor until it locks/unlocks. Can anyone shed some light on all of this for me? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
