Yours maybe similar.The BICS Controller provides power to the coil in the Brake Relay (which has wire colors Red, Black, White, Pink/White).The white on the brake relay wire receives power from the Brake Fuse and then powers the pull coil on the Brake Solenoid.The Brake Solenoid Pull Coil on mine is spec'd as 0.4-0.5 ohm white to black.The Brake Solenoid Hold Coil is spec'd at 10-11 ohms.I would check the following when it stops working:1. Make sure you have power leaving the Brake Fuse. going to Red/White on the Brake Relay.2. Make sure when you drop the seat bar the Brake Relay should close and provide power for a couple seconds on the white wire that goes to the pull coil on the Brake Solenoid. Easiest to check it at the solenoid while sitting in the seat.3. Unplug the Brake Solenoid and check the resistance values on the Pull and Hold Coils</blockquote>
