CORRECTIVE ACTION - Continued
CAUTION
Electrical power must be shut OFF from circuit before continuity can be checked.
Failure to comply with this caution may result in damage to test equipment or
electrical system.
NOTE
A reading of infinity indicates an open circuit.
2.
Set multimeter to ohms position.
3.
Place negative (-) probe of multimeter on position 6 of digital controller wiring harness connector
J3 (Figure 16).
4.
Place positive (+) probe of multimeter on position 1 of WINCH IN solenoid connector (Figure 16).
Check multimeter for continuity.
5.
Place negative (-) probe of multimeter on position 36 of digital controller wiring harness connector
J3 (Figure 16).
6.
Place positive (+) probe of multimeter on position 2 of WINCH IN solenoid connector (Figure 16).
Check multimeter for continuity.
a.
If continuity is not present at one or both readings, repair or replace digital controller wiring
harness. Refer to TM 9-2320-435-10 or TM 9-2320-425-10.
b.
If continuity is present for all of the readings, proceed to next Malfunction.
MALFUNCTION
WINCH IN Directional Control Valve is Faulty (Model B Only).
CORRECTIVE ACTION
CAUTION
Electrical power must be shut OFF from circuit before continuity can be checked.
Failure to comply with this caution may result in damage to test equipment or
electrical system.
NOTE
Digital controller and cab control box are not repairable, therefore, it is necessary
to test digital controller and cab interface wiring harnesses, switches, solenoids,
and other components to identify possible faults other than digital controller and
digital cab controller.
1.
Set multimeter to ohms position.
2.
Place negative (-) probe of multimeter on position 1 of WINCH IN solenoid (Figure 17).
