Check Control Panel. (cont’d)
NOTE:
Voltages specified in Procedures are based on a
voltmeter with a resistance of at least 10,000
ohms per volt. Readings marked with * will differ
if a lower resistance voltmeter is used.
(2) As (1) but with MAXIMUM selected.
All pins zero volts except:
C1 - 3, & - 5 to be aircraft voltage.
C1 - 2 to be 7.5 volts* initially, changing to zero as
pressure rises.
All pins on connector C2 as (1).
(3) As (1) but with NORMAL selected.
All pins zero volts except:
C1 - 3, & - 4 to be aircraft voltage.
C1 - 2 to be 7.5 volts* initially, changing to zero as
pressure rises.
All pins on connector C2 as (1).
(4) As (1) but with WINDSHIELD 1 selected.
All pins zero volts except:
C1 - 3, - 6, & - 8 to be aircraft voltage.
C1 - 2 to be 7.5 volts*.
All pins on connector C2 as (1).
(5) As (1) but with WINDSHIELD 2 selected.
All pins zero volts except:
C1 - 3, - 9, & - 11 to be aircraft voltage.
C1 - 2 to be 7.5 volts*.
All pins on connector C2 as (1). OR
2. Remove Control Panel and bench test.
(6) As in (1), but with PUMP 1 selected.
All pins zero volts except:
C1- 3 and - 7 to be aircraft voltage.
C1- 2 to be 7.5 volts*.
All pins on connector C2 as (1).
(7) As in (1), but with PUMP 2 selected.
All pins zero volts except:
C1- 3 to be aircraft voltage.
C1- 2 to be 7.5 volts*.
All pins on connector C2 as (1).
Check Tank Contents Transmitter. Remove seat/wing panel(s) to obtain access.
1. Disconnect connector C3. Measure resistance
across contents transmitter leads at pins C3 as fol-
lows:
All pins to ground > 10 megohms
Pin 1 to Pin 3 = 10,000 ohms (nominal)
Pin 1 to Pin 7 should vary from 1/2 the resistance
between Pins 1 & 3 (5,000 ohms nominal) with tank
empty to approximately 3000 ohms with tank full. OR
2. Remove Contents Transmitter and bench test.
