The Bus has been parked for about 7-10 days. Yesterday I removed the harness for the lights and sensors for emergency exists.
Now the air brakes wont release. No alarms sound. Just the brakes wont release. Both tanks are at 120psi and I can hear the air cycling through as I press on the pedal. The pressure release valve also releases normally.
While itís possible that the airbrake release switch is connected to the emergency exit circuit, I donít know this for sure.
Probably. Installing a hitch receiver today. So when thatís done Iíll track down the circuit. Determine if itís an open or close circuit and fix it. Fairly easy to determine if the switch is open or closed when static or activated.
I'm surprised there isn't an audible warning that a door is "open". Surprising also that yours allows you to start the engine with an "open" door. Mine are all connected to the starter, open door, no turning the motor.
