b.
Use an analog multimeter to check resistance between the
points listed below. The meter should read less than 25 ohms
when the meter is connected with positive lead on connector
pin, and should read greater than 10K ohms when meter is
connected with negative lead on connector pin. If not the
diode or wire is defective.

PRESSURE TRANSDUCER MALFUNCTION
100.
If the pressure transducer is suspected of malfunctioning, test the transducer
as follows.
a.
Disconnect battery.
Disconnect one wire from the transducer (19, figure 4-55).
b.
c. Check resistance between transducer terminals. Resistance
should be approximately 73 ohms with no pneumatic output. If
resistance is not approximately 73 ohms, replace transducer.
d.
Connect battery and operate system with pneumatic output
terminals, then shut down system.
e.
If resistance was not approximately 10 ohms with pneumatic
output, replace transducer.
