Help! Low air Buzzard?

Hi JJ, HA. I was going to say, look out for those "low air buzzards", as I hit a freakin' turkey ( about the size of a buzzard) with my 4 wheeler once, shattered the windshield.
ANYWAY, unless they changed something, I was told, preferably both, but 1 or the other should be enough to pass. I'm confused what would cost so much. All it is, is a pressure switch, in line with your gauge, with a 12v buzzer, usually under the dash( so you can hear it) and when the pressure drops, it sets off the buzzer. At least that's how it was with the old iron. Who knows now?

 

Ah, I probably jumped to an erroneous conclusion here, but come on man, you said two DOT cops were talking and you heard

Now I know that it would seem like some drivers, even truck drivers are BLIND but I find it hilarious that a DOT cop would say something like that, unless it was in jest. . .

 

You should keep an eye on all gauges to make sure everything is ok if you do this you will know what is going on. If all else fails you will know your air is to low when the brakes lock up.

 

Probably would depend on year of truck. I would imagine technically it should be compliant with the date of manufacture. Some of the trucks I used to drive when I first started had no buzzer or light, just a mechanical flag that would drop down in front of you if air pressure was low.

 

The OOS criteria reads as follows:

Low Air Pressure Warning Device


Low air pressure warning device missing, inoperative, or does not operate continuously if either the primary or secondary reservoir is 55 psi (379 kPa) and below, or 1/2 of the governor cut-out pressure, whichever is less. (393.51(c))

NOTE: If either an audible or visual warning device is working as required,
vehicle should not be declared out-of-service.

 

Federal laws are some times left to the states to interpret and enforce, they do not always do that the same. I thought the low air alarm (audible) was required to come on by 65 PSI. Thanks for the reeducation! A company I previously worked for had a truck put out of service in (?) a mid or north Atlantic state. The light worked but the alarm did not and had to be repaired or towed. Had a driver in training from S.C. , the company sent him with a trainer to S.C. to take his test in a Volvo White Heavy Truck Corp. truck the alarm would not work with the key on engine off but the light did. The buzzer came on the same as the light if the engine was running. All the other trucks were the same. Installed a old buzzard box like old blue to the left has and it passed. If the only thing wrong with your circuit board assy. is the alarm anybody that knows anything can install a buzzer pretty cheaply. Some times it's not worth the fight even if your are right.

 

when a low air buzzard needs to go to higher altitudes they buy a ticket ....

 

Boy 6days, what you said brings back memories. I cut my teeth on a 1957 H model Mack. It also had a mechanical arm that dropped down in front of you for low air pressure. When pressure was built up sufficiently you could push the arm back up and it would stay up.
Lol........buzzard the guy says.
