m35a2 air warning buzzer

[anthony3478]

Looked a a m35a2 today, just wondering once you have started the truck whats normal time til the buzzer stops sounding?

2-3 minutes

Assuming your air gauge is correct, I believe it will stop buzzing around 60 psi... check your TM for sure though.

Jump out of the truck and do a walk-around while the buzzer is doing it's thing. You won't have to listen to it, and you'll know there aren't any flat tires and stuff like that.

I always flip the accesories switch off unitl the Pressure builds

 

[Lex_Ordo]

Generally, I gIve the start button a push, and then hop out, pull the wheel chock and do a quick go around. By the time I'm done with that, and gone back into the house to grab my gear, not only the buzzer has stopped, but he truck is warmed up so I can leave.

But right around 60 psi, the buzzer will shutoff. Just a few minutes.

I checked mine today after tatally draining air out of system to check air pack. 50 seconds and buzzer was off.

Fify seconds that seems like an eternity if you sit there and listen to it...
I wait for the oil pressure gauge to come up, then flip the master switch off, then do a final walk-around and bulb check. It's usually done by the time I'm done.

Isn't that hard on the alternater?

I've always wondered about that. If you turn the accessories switch off where does the juice coming out of the alternator go?

 

[Jake0147]

It hasn't blown up yet, but if it's gonna then I'm all ears...

The charging lead from the alternator to the batteries, as well as the ground circuit for the alternator don't go through the master switch, so the "juice" has some place to go. It could possibly turn off a sensing voltage and cause it to charge at full rate. If it were "full fielded" in this way it should not an issue for a short time... but it could be a big issue if you were to walk away for some time.
I'm prolly going to have to resort to the manual on that now that you say this. If that's not conclusive I might have to dig the multi-meter out and poke around some...

juice

...... where does the juice coming out of the alternator go?

It goes back into the alternator to charge the pressure in the magic smoke container!

You could always add an air stem and pre-charge your tanks if you have an air compressor at home. Would also save some wear and tear on your truck's compressor along with it being dryer air.

I had wired up a "silence" button a while back. I'll have to draw up a diagram for it. It functions in a manner that the light and buzzer come on with low air then you press the button which silences the buzzer but allows the light to stay on. It stays in the "silence" mode till air pressure builds up to over approx 60 psi. when the buzzer would normally shut off then resets back to "normal" mode. Pretty nice add on and cheap too.

I'm not saying that it "is" a problem --- I just don't know. I remember when I installed the battery isolator switch on my cruiser the instructions warned about switching/selecting batteries when the engine is running because it could cause alternator damage. I wasn't sure whether the same applied to a Deuce or not.

When you have a flux capacitor like I do you don't need a magic smoke container

 

[SasquatchSanta]

I know this is not original equipment but I did away with my buzzer and installed a wig-wag.

It's mounted above the drivers side windshield. When the air pressure gets low an arm drops down to signal a problem. They were standard equipment on trucks back in the 50s.

How do you check your bulbs with the master switch turned off? What am I missing? Maybe I am old fashioned but I like the sound of the buzzer.

The light switch work independently of the accessory switch, so you can operate your lights without the engine running.

To be different I installed a device (a turn signal flasher) that interrupts the buzzer, so that it goes beep....beep...beep...etc, a much more tolerable sound. The turn signals are also wired into the buzzer to buzz when used....

I leave the master switch on!............... When you turn the master switch off, the intank pump no longer runs. So then the supply pump on the IP is doing double duty to suck the fuel all that way from the fuel tank. My, But i dont think that turning the switch off is a good idea.
