TEST OR INSPECTION
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.
If reading not as
1CR9 or wire E21A20
1CR11 or wire P15B20
1CR10 or wire P16B20
1CR4 or wire X21B20
1CR3 or wire X22B20
1CR6 or wire P4OA20
1CR5 or wire X46B20
1CR1 or wire X24B20
1CR2 or wire X23B20
PRESSURE TRANSDUCER MALFUNCTION
If the pressure transducer is suspected of malfunctioning, test the transducer
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.
Connect battery and operate system with pneumatic output
terminals, then shut down system.
If resistance was not approximately 10 ohms with pneumatic
output, replace transducer.
