01 Thomas MVP Vandalock / Buzzer

Howdy all.


I'm curious if anyone here who has experience with the rear engine Thomas MVP line can tell em if the warning buzzer for the Vandalock system is the same as the low air pressure warning for the air brake system? I'm working on acquiring one that is failing to start with the key (although there is power) and am told there is an active buzzer going off when the key is off and trying to determine if the buzzer is the same noise for Vandalock and air brakes? Most of the commercial vehicles I've driven had a constant loud beep instead of a buzzing noise. THanks in advance.

Low air pressure alarm is factory installed and part of the brake system . Vandalock is school bus specific and an add-on. I can't imagine them tying the two together. Of course, I could be wrong...

Yeah I may have jumbled my words, I was more concerned with the low air alarm and the Vandalock alarm sounding the same, and not being able to distinguish between the two. On most recent trucks I've driven (94+) the low air was a constant loud beep, not a buzz, so I'm hoping the "buzz" is just the vandalock system and will point me to the problem.

My low air alarm also beeps, loudly. Everything seems to have its own particular, annoying, sound. My "Levelers Down" is a alarm is the loudest, by far

No. They are not the same.

The air buzzer should go off if you wait. Also you can watch the air gauges or look for the red light on the freightliner dash.
The red light for air is a red circle with a prong at 12, 4, and 8 oíclock.

Peace

When I got my bus, it had latches and locks. For the engine to start doors/windows need to be latched but not locked.

You can always start the bus from the engine compartment.

Turn the dash key to ignition.

Open lid for engine compartment.

Hold the lid button(upper right hand corner) and press the start button.

Clackity clack!

Thanks for the replies. It wont turn over at all, so I'm guessing an interlock or fuse or some other wiring snafu. I'll figure it out though. Going this weekend to look.

That's what I'm hoping for. Wasn't sure if the rear would by pass the Vandalock system or other interlocks. Obviously neutral safety would still work from the rear, but the pesky ones.
