gearhead204 Posted February 20, 2014 Share Posted February 20, 2014 dave I cant say for positive but a 73 was not required by law to have a buzzer' it should have 2 visual.1 primary air and 1 secondary air pressure gauge then a wig-wag that drops a red flag in front of the driver at or below 60p.s.i. somebody correct me if I got this wrong Quote Link to comment https://www.bigmacktrucks.com/topic/34743-low-air-buzzer-senser/#findComment-233730 Share on other sites More sharing options...
konk Posted February 21, 2014 Author Share Posted February 21, 2014 Thanks for the reply. My 73 r600 has only 1 air gauge. Thanks Dave Quote Link to comment https://www.bigmacktrucks.com/topic/34743-low-air-buzzer-senser/#findComment-233749 Share on other sites More sharing options...
HarryS Posted February 21, 2014 Share Posted February 21, 2014 I don't know about the Rs but I just finished doing the wiring harness on my 60 B and there is a buzzer in schematic located on the driver side dash/steering column support. The air line sensor runs off the air manifold on the passenger side of the firewall.

doubleclutchinweasel Posted February 24, 2014 Share Posted February 24, 2014 Pretty sure it has one. Every R i've ever been in did.Probably under the dash, or on the inside of the firewall.I'll look in my service manual tonight, and see if I can find you a picture.

blackdog2 Posted February 24, 2014 Share Posted February 24, 2014 Usually right by the clutch pedal is the sensor the buzzer is right above . Quote Ed Link to comment https://www.bigmacktrucks.com/topic/34743-low-air-buzzer-senser/#findComment-234422 Share on other sites More sharing options...
