ORGANIZATIONAL TROUBLESHOOTING CONTINUED
TEST OR INSPECTION
1. ENGINE FAILS TO CRANK WHEN STARTER IS ENGAGED CONTINUED
Although ignition lock switch must be on and battery ground cable connected to test
electrical circuit voltage, turn off ignition lock switch and disconnect battery ground
cable before doing resistance tests or replacing parts. This will keep you from getting
shocked and prevent damage to parts and equipment.
Do not smoke, use open flame, or allow sparks near batteries. The mixture of oxygen and
hydrogen gases released from batteries is highly flammable and can explode causing
serious injury or death.
Using multimeter set to 30 vdc scale, place red probe on positive ( + ) battery terminal (1) and black
probe on negative (-) battery terminal (2). Check for 11 to 13 vdc on multimeter.
a. If multimeter reads 11 to 13 vdc, go to step 10.
b. If multimeter reads less than 11 vdc, replace defective batteries (page 2-692).
Using 1/2-inch open-end wrench and 1/2-inch box wrench, loosen nut (3). Take terminal clamp (4)
off of negative (-) battery terminal (2). Using multimeter set to RXI scale, place red probe on
terminal clamp (4) and black probe on terminal (5). Check for 0 ohm on multimeter.
a. If multimeter reads 0 ohm, place terminal clamp (4) onto negative (-) battery terminal (2) and
tighten nut (3). Using 112-inch openend wrench and 1/2-inch box wrench. Go to step 11.
b. If multimeter reads more than 0 ohm, replace battery ground cable (2-696).
