I can't get the brake solenoid to release. Here is the troubleshooting that I've done. I ohmed out the solenoid and it is as it says it should be on my wiring diagram. Brake relay is also good. I continuitied the white wire from the solenoid plug to the brake relay and also the pink with white wire from the relay to the BICS box. Both are ok. I'm getting about 7.5 volts on the red wire (hold coil) at the solenoid but no voltage on the white wire (pull coil). I can get the solenoid to release the parking brake by putting battery voltage in place of the pink with white wire at the brake relay. Also, I pulled my traction lock override button out and I can't seem to get any continuity across it. Could that be bad and causing this? Also, no light or flashes on the BICS Traction light. Any and all help will be much appreciated, thanks in advance.
