Air pressure gauges register the pressure in the pri-
mary and secondary air systems. Normal pressure
with the engine running is 100 to 120 psi (689 to 827
kPa) in both systems.
Air pressure gauges are required on all vehicles with
air brakes. A low-air-pressure warning light and
buzzer, connected to both the primary and secondary
systems, activate when air pressure in either system
drops below a minimum pressure of 65 to 75 psi
(448 to 517 kPa).
When the engine is started, the warning light and
buzzer remain on until air pressure in both systems
exceeds minimum pressure.
