Ever see inside the Protective Control Box?
Looking at Plode's pictures, it doesn't look to me like that would do a very good job at protecting from reversed batteries. The diodes there look like the go across the coil and act as suppression diodes to bleed off the energy in the coil when deactivated. If no other diodes are added the...- hklvette
