I see two red wires; do I need to connect both of them to power? Why?

Yes. The small gauge wire supplies power to the processors and logic on the PCB (printed circuit board), while the large gauge supplies power directly to the solenoids through on-board relays.

My shaved door handle kit blows fuses. What is wrong?

Please follow the instructions below to resolve this issue:

  1. Make sure you are using a 30A fuse in the large gauge red wire, and a 5A fuse in the small gauge red wire.
  2. Make sure you have a good chassis ground.
  3. Check all wires for corrosion or cuts/scrapes/pinch spots that could cause shorts.
  4. Run the power wires directly to the battery (do not use the vehicles wiring harness.)
  5. Check the output of the main unit:
    1. remove the large gauge yellow and brown wires (be sure to leave the large gauge red wire connected.)
    2. test the spade terminals for 12VDC output with a voltmeter or test light.
    3. if the voltmeter reads 12VDC or the test light lights without blowing the fuse:
      • you know the problem is in one of the solenoids or the wires of the solenoids.
      • Check wires and solenoids.
    4. If the fuse still blows:
      • the brain may be defective.
      • If within warranty date, return to point of purchase for warranty.

How do I identify if my kit has solenoids or actuators

Solenoid Actuator

Return to top
My vehicle needs the solenoids to push and not pull. What can I do?

In this situation you have two options:

  1. The SPAL 40-pound solenoids are large electromagnets and are designed only to pull. However, you can use a pulley system to convert the pulling action into a pushing action. Please see the illustration below:
  2. If you do not require 40-pounds of force, as with many BearClaw style latches, you may want to consider our SPAL lock actuators. These actuators will provide 8-pounds of force in both the pushing and pulling strokes.
