{"text":"Question. This truck has an all electric APU, it works great, auto start and stop works fine. The problem I’m having is after I’ve had the engine shut off about 2 hours, my air pressure drops below 60 and the alarm starts beeping, I’ve got trailer and tractor brakes set, going to have the shop try to find where my leak is when I get home, but does anyone know how to shut off that alarm clock until I can get the leak fixed?","videos":"[]","link":"{}","pics":"[]","canComment":true,"externalShare":false}
