    Im in a prostar, non idle battery pack apu. I have an air leak, im losing 60 psi over two hours at the parking knobs, i believe. If i run the apu, and the air gets low the low air alarm beeper goes off when the air is low, which is wakin me up every two hours and its getting on my last nerve. Is there a fuse i can pull or wire i can disable to disable it?

    Ignition key has to be in 'run' position for APU to work?

    Get it fix, or wait till you get an inspection ,get a fine then get it fix.

    Also why do you have to turn your truck on to run apu?

    How about a logical solution? Go get it repaired. DOT will have a field day if you get an inspection.

    You had to have the ignition in the off position or I did in my 3 different trucks I drove.

    Easy fix. When you stop for your break, pump down the air til it is empty. Key off, no buzzer.

    Yes igg in off position. If apu isnt on the alarm doesnt sound. If apu is on the alarm sounds when air gets low. "Auto start stop" button on.
