Joey Mack Posted January 15, 2023 Share Posted January 15, 2023 there are several of them,, check to see if any of the wires to the pressure switches behind the pedals are un-plugged or chafed through causing a 'short' Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-521370 Share on other sites More sharing options...

Joey Mack Posted January 15, 2023 Share Posted January 15, 2023 With the air pressure up above 85PSI. duplicate the issue, and while it is buzzing,, work the turn signal wand left and right and around in circles to see if there is a short in the signal wand. They are linked.. Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-521372 Share on other sites More sharing options...

Joey Mack Posted January 15, 2023 Share Posted January 15, 2023 A bad buzzer is possible, but I am thinking a short, or backfeed in the brake light circuit.. you can unplug each pressure switch , one at a time and see if one of those stops the buzzing issue..

mechohaulic Posted January 16, 2023 Share Posted January 16, 2023 off the walll ; but I'm old.. by chance is the buzzer going off with brake application because there is an air leak?? at 120 lbs of air / press brake pedal;; how fast/ low does air go down?? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-522082 Share on other sites More sharing options...
masterwelder Posted January 25, 2023 Share Posted January 25, 2023 My 2001 RD buzzer buzzes when the turn signals or hazards are used. I think it’s a reminder feature. I would say if the buzzer comes on with the brake something is back feeding into the turn signal circuit. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-523727 Share on other sites More sharing options...
Joey Mack Posted January 25, 2023 Share Posted January 25, 2023 A faulty turn signal switch/wand can cause issues like that, and tail light wires that are shorted together and so on.. I agree to it being a backfeed.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-523728 Share on other sites More sharing options...

I think it’s just dead haven’t even had the key switch on in a number of years it may just start performing after a few swift kicks I even gave the warning light I removed from a later model parts truck years ago that goes along with the buzzer if I live long enough to ever install it… Bob Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-523896 Share on other sites More sharing options...

It was driving us crazy when we finally found the problem somebody put a single filament bulb and one of those tail lights that were supposed to have a double filament Bob 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/31630-low-air-buzzer-install/page/2/#findComment-523901 Share on other sites More sharing options...
