Another newbie question

Just cut the + wire close to the annunciator and connect a switch between the two ends.

You would label the switch as for service only.

If you don't want to add a switch, or locate the CB to trip, turn off the bus battery switches in the rear.

There are numerous times when it is necessary to turn off the key and release the parking brake so I surmise there is a quick way to extinguish the warning sound.

Jon, Good Idea. I was at Prevost in Jacksonville and several Buses were up in the air with tires off, brake jobs, etc and none of them had the alarm going off. Probably because they turn off the battery switch. Thanks.

So how many jacks does one need for a bus?

[Kevin Erion]

At Prevost Mira Loma they turn the CB off!
Very easy, just remember to reset before driving!

[Jon Wehrenberg]

Depends on what you want to do.

If all you want to do is pull a wheel, one.

If you want to work under one end only, two.

If you want the entire bus supported, four.

It gets complicated after that because if you want to be under the bus, and raise an axle, such as to change air bags, or work on brakes then you need to support the bus, plus lift the axle.

I would strongly urge you to never get under your bus unless and until you have it properly supported, and you really know what you are doing. There is no chance I could consider getting under a bus even if it was supported unless I knew the concrete beneath it can handle the weight concentrated beneath the supports and that the ground was absolutely level so it did not shift and fall.

Simple solution on the later shells, with the bus properly supported as Jon correctly keeps driving home, leave the key on, release the brakes and do your work. If your short on air, put shop air to the rear fill valve and rock on. Leaving the key on won't hurt anything for a reasonable period of time. Now before you start throwing darts at me, this is assuming your not working on the drive axle brakes, cause if you run out of air, the spring brakes are coming on! I have quick connects on the aux air and rear fill so I can just hook my shop air direct.

Are we beating this to death or what? We agree the beeper only functions with the key off, right? Turning off the chassis batteries will turn it off OR pulling #68 relay in the front junction box will also.
