Expert Reply:

It sounds like you may have wired your setup in such a way that the battery is somehow putting voltage on the brake output circuit which is why your brakes are locking up. Check the third page of the installation instructions I attached to see the wiring diagram on how it should be wired up and compare it to your setup.

You should also check to make sure that the plunger is properly installed into the switch.
