MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
Test 2. Test high beam selector switch.
Step 1. Check high beam selector switch input voltage.
a. Remove lead 16 from high beam selector switch.
b. Set multimeter to a range that will measure 24 volts.
c. Check lead 16 contact end for battery voltage.
d. If voltage is present, go to step 2.
e. If voltage is not present, go to test 3.
Step 2. Check high beam selector switch continuity.
a. Remove lead 17 from high beam selector switch pin L. Remove lead 18 from high
beam selector switch pin H.
b. Set multimeter to RX1 scale. Check continuity between input pin and pin L.
c. If continuity is not found, push high beam selector switch to change from HIGH
to LOW. Recheck continuity.
d. Replace high beam selector switch if no continuity is present (para. 4-35).
e. If continuity is present, check continuity between pin H and input pin.
f.
If no continuity is present, push high beam selector switch to change from LOW to
HIGH. Recheck continuity.
g. Replace high beam selector switch if no continuity is present (para. 4-35).
