Anyone know how to bench test a E-Locker?

EWAYota · 10-02-2009, 07:04 PM

I've got one sitting in my front axle that I just finished modding for it, and I've got a line on another one for my rear but the seller isn't sure if the motor works. I'd like to test both before ordering up 12v guys e-locker harness and switches.

Anyone know the best way to check the motor for functionality? I've heard of hooking it straight up to a battery but also heard that wasn't the best idea.

Suggestions?

Might set up the simplified wiring as shown below:

The 12V guy kit doesn't have any relays so it relies on the internal limit switches in th e-locker. Read into the link below for details. Quick and easy way to test the motor with an alligator clip, two pieces of wire & in my case a Makita 9.6V battery

There are two connectors on the locker. There is a smaller 2-pin connector which connects to a switch that closes when the locker is actually locked, and a larger 5-pin connector which connects to the actuator motor and limit switches.

Pins 1 and 2 go to the motor. Applying +12v to pin 1 and ground pin 2 locks the unit. Reversing the polarity unlocks it.
Pins 3, 4, and 5 go to a limit switch, and are used to stop the motor before the mechanism reaches its mechanical limits. Pin 3 is connected to pin 5 unless the unit is locked. Likewise, Pin 4 is connected to pin 5 unless the unit is unlocked. Notice that while the unit is in transition between states, both pins 3 and 4 connect to pin 5.
So to lock the unit, put the alligator clip across pin 3 and pin 1. Apply +12v to pin 5 and ground pin 2. While the unit is transitioning from the unlocked to the locked state, pin 3 is connected to pin 5, and so pin 1 receives +12v. Once the unit determines that it has moved far enough to be locked, pin 3 becomes disconnected from pin 5, pin 1 no longer receives +12v and so the motor stops.
Likewise, to unlock the unit, simply put the alligator clip across pins 2 & 4 and apply +12v to pin 5 and ground pin 1. Once the unit is unlocked, the connection between pins 4 & 5 is broken, and pin 2 no longer receives +12v.
Using the limit switch will prevent the unit from reaching its mechanical limits and will avoid the problems I encountered.
