What's with this box

[cadillackid]

its a navistar part number so its not a door beeper or such... something else is in alarm... if the cluster goes back like dead pirate's then that beeper will stay on all the time.. if you get water leak into the gauge cluster it will beep..



also it will beep if one of your brake pedal switches goes bad.. and will set a code 247. that doesnt like the WARN light but causes that beeper to go off constantly..



if the bus hasnt been run for awhile it will beep constantly while the air is still pumping up to about 60-70 PSI..



unless your gauge panel is broken I would suggest trying to figure out why its beeping rather than just destroy it by flicking it...



check the connectors on back of your gauge cluster anbd make sure they are plugged in good and tight..



have someone with the computer interface plug in to your diagnostic connector or perform a flash code diagnosis on your own. (turn the key to ON.. press the DIAG button under the dash and the WARN LIGHT will flash you any error codes)...

Thanks drove it today and after getting going the beeping stopped I think it may be some type of low battery warning cuz the battery seems to be affected by the cold weather on another note got it insured today so that's one thing out the way

It might be the buzzer that reminds the driver to check the bus for kids when they turn the motor off. See if there is a button on the inside back wall of the bus. I had to disconnect one of those before.

The buzzer is a low air buzzer. Sure seems to me like the low air switch that drives the buzzer has gone bad. Examples:

Probably the emergency hatch warning if you have opened it probably not shutting right I had to disable mine in the power control box by the driver.

I’m thinking that the low air switch mounted on the air tank or somewhere near by is either broken or jammed or truly not getting air pressure, causing it to complete the circuit back to the low air buzzer. Examples:

Was going to reply to your original issue until I saw the picture of the buzzer. I know on some of my door buzzers the screw that mounts it to the bus is the grounding screw. If the box isn't mounted your bus won't start. But your buzzer is under the dash, have no clue what it is for.
My bus is very similar to yours, curious to your screen name, what's the E?
Here's mine see the side.��

Hey everybody sorry it took so long to reply I finally figured it out it's some
thing to do with a low battery is why I'm getting the beep I also think it beeps if there is low air pressure mine was beeping due two low battery when I bought the bus it only came with one battery witch has a bad cell in it I think

[E420]

Bought a second battery for the bus haven't had a problem since

If you replaced it with a new battery you should replace the other as well. The old battery will kill the new one especially if it has a dead cell.

Always replace in pairs. I just changed my batteries out with 31 series 900+ cca.
