Thanks for your question Garry. If you replaced the # DM65MV on your Demco Air Force One and the indicator light is staying on, I would make sure the actuator cylinder is fully returning when the brake pedal is released. If the cylinder is getting hung up, the magnet may not be returning to the correct position. You may also need to adjust the reed switch itself up or down the cylinder to ensure the magnet is not misaligned.
Are you having issues with the # DM23MV you previously purchased?
