BB-200 Positive Switching Bump Box


Ground Switching for One Wire Solenoid

The BB-200 is used on trans brakes that only have the positive wire available for connection, and the ground is inside the transmission, also known as a “1 Wire Solenoid”.  The BB-200 interrupts the positive battery voltage signal to the solenoid to allow for precise movement when the “Bump Button” is pressed.  The “Bump” is easily adjustable with two dials on the face of the unit, to allow for easy adjustments without confusing digital interface.

  • 10 millisecond increments – coarse knob (can easily be changed if another increment is desired)
  • 3 millisecond increments – fine knob (can easily be changed if another increment is desired)
