MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
Step 4.
With engine running, test stator assembly (alternator) output by disconnecting engine wiring
harness connector from regulator (see paragraph 4-129). Using a multimeter set to DC voltage,
measure stator assembly output.
If stator assembly output is within 12 V dc ± 1 V dc, replace damaged regulator (see
paragraph 4-129).
20. BATTERY OVERCHARGES.
l Remove all jewelry such as I.D. tags, rings, bracelets, etc. If jewelry contacts battery
terminal, a direct short will result causing instant heating of jewelry which will result
in serious injury or death to personnel.
l Battery acid (electrolyte) is extremely dangerous. Always wear protective goggles
and rubber gloves when performing battery checks or inspections. Serious injury
to personnel will result if battery acid contacts skin or eyes.
l DO NOT perform battery system checks or inspections while smoking or near fire,
flames, or sparks. Battery gases may explode, causing serous injury or death to
personnel.
NOTE
Refer to engine wiring diagram for assistance (see paragraph 4-135).
With engine running, test stator assembly (alternator) output by disconnecting engine wiring harness connec-
tor from regulator (see paragraph 4-129). Using a multimeter set to DC voltage, measure stator assembly
output.
If stator assembly output is within 12 V dc ± 1 V dc, replace damaged regulator (see
paragraph 4-129).
If stator assembly output is not 12 V dc ± 1 V dc, replace damaged stator assembly (see
paragraph 4-116).
