CORRECTIVE ACTION
OUTRIGGERS
12. ALL OUTRIGGERS FAIL TO OPERATE.
Step 1.
Check that outrigger control panel power switch is set to ON position.
Step 2.
Disconnect cable from input side of circuit breaker box. Measure for 24 V dc between circuit
breaker input box cable and ground.
Replace defective connector if 24 V dc is not present (para 4-20).
Step 3.
Disconnect cable from output side of circuit breaker box. Connect input cable to input side of
circuit breaker box. Measure for 24 V dc between output connector of circuit breaker box
and ground.
Replace circuit breaker box if 24 V dc is not present on output side of circuit breaker
Step 4.
Connect cable to output side of circuit breaker box. Disconnect cable on output side of
master relay box. Measure for 24 V dc between output connector of master relay box and
ground.
Perform step 5 if 24 V dc is present.
Perform step 6 if 24 V dc is not present.
Step 5.
Check for defective or damaged wiring harness.
Replace defective or damaged wiring harness (see FO-1).
Step 6.
Connect cable to output side of master relay box. Disconnect small connector linking master
relay box to outrigger control box. Measure for 24 V dc between connector and ground.
Master relay box is defective and must be replaced if 24 V dc is present (para 4-23).
Step 7.
Check for defective control panel and power switch.
Replace defective control panel or power switch (para 4-22).
13. ONE OR MORE (BUT NOT ALL) OUTRIGGERS FAIL TO OPERATE.
Step 1.
Check for defective or damaged upper and lower outrigger limit switches.
Replace defective or damaged upper or lower outrigger limit switches (para 4-24 or 4-
NOTE
Steps 2 through 5 check for defective outrigger relay box panels.
Step 2.
Check for 24 V dc to ground at cable 100. Connect cable.
Check wiring harness if 24 V dc is not present.
