  2. Ignition OFF, check for less than 1.0 ohm of resistance between ground circuit terminal 4 and ground.
    • If greater than the specified value, test the ground circuit for a short to voltage or open/high resistance.
  3. Ignition ON, test for 9-12V, between the B+ circuit terminal 2 and ground.
    • If not the specified range, test the control circuit for an open/high resistance.
