Dang the Buzzer Alarm won't go off....

Hi All,

I have a 1998 26' bluebird bus. The Buzzer alarm in the control panel by the drivers side window is buzzing, and I don't know why.

If the key is on or the engine running, the alarm is going. Its very annoying. I checked all the doors, the roof hatches, everything I could think of - everything is securely closed.

I eventually disabled the alarm by disconnecting the wire, but I am worried that it is trying to tell me something important, and I don't want to ignore the actual cause of the buzzing. Any ideas?

(FYI - This buzzer has always been a little mysterious to me, for example in the past it has taken me a long time to figure out that the emergency hatch wasn't closed all the way. )

Any help would be appreciated!

Thanks,
Hailey

With ours, it usually works to walk back and open and close the back door latch. I think they designed it that way so that the bus driver would always have to walk to the back of the bus and check for any remaining children before leaving the bus.
If the the latch thing doesn't shut it off, try turning the key a little to the left and right. Sometimes it gets stuck in the halfway on position.
You're right that it's all a little mysterious. I think we'll disable ours, too, as soon as we get the chance.

You can look for videos on you tube for information on how to disable your interlock system. Normally if the buzzer is going off you can't start the bus. The interlock disables the starter.

The rear doors can not be locked while starting the bus, much the same as the hatch must be latched. It's a safety system built for misschevious kids.

I keep hearing about this interlock system, and am not really sure that I have one, as none of the doors in my bus have locks. Also, I've always been able to start the bus while the buzzer is going. Perhaps a previous owner already disabled the interlock system?

All of the door latches are very strait forward levers on the inside.
When moved, they move the latches on the outside when moved and vise-versa.

The only locks I have are bolts that can be put into holes that have been drilled in the levers and allow them to be bolted to the door handle so they can't be moved.

I will watch the videos you suggested and see what I can learn.

Thank you!

Thanks, I will try this! I'm not sure how my bus would know if I open it from the inside or the outside, but its definitely worth a shot!

milkmania, I'd say your bus may not have had an interlock because it wasn't built to be a school bus.

As for the rest of us, myself included, our interlocks still work at varying levels. I've never seen two of them disabled the same way because it seems buses vary quite a bit. I like the reminder for the door latches, but not disabling the starter. If my back door is latched I can't start the engine. If either rear or lift doors are open I can't start the engine. Yeah, I probably shouldn't drive with the rear or lift doors open, but you never know.

And yes, I get it that your buzzer goes off unless you disable it. The real issue, of not being able to start your engine doesn't apply. Buzzer disabled, I can't say if there's a problem from that specifically. I've done the same disconnect with buzzers in the past, and nothing notable happened.
Your bus does start and you've disconnected the buzzer itself. I mean, you got the noise to stop and your bus still runs. That's a win. I think you've solved your own question.
If you're asking if disabling your buzzer will start a fire and burn down your bus, you'd have to ask an electrician.
