Although KEY SWITCH must be on and battery ground cable connected to test electrical circuit
voltage, turn off KEY 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
Scrape painted surfaces to bare metal before connecting test leads to ensure correct multimeter
Check batteries as follows: Remove battery box cover (page 2-424). Set multimeter to 20 vdc
scale. Connect red test lead to positive terminals (1 or 2) and black test lead to ground. Check
for 11 to 13 vdc on multimeter. Disconnect test leads.
a. If multimeter does not read 11 to 13 vdc, remove and clean battery cables (page 2-
b. If multimeter reads 11 to 13 vdc, install battery box cover (page 2-424) and go to step
Disconnect batteries (page 2-424). Check 14-6 wire (3) for loose, corroded, frayed, or broken
If 14-6 wire (3) is loose, tighten nut (4) using 3/4-inch open-end wrench.
b. If 14-6 wire (3) is corroded, unscrew and take off nut (4), lockwasher (5), and wire
terminal (6) using 3/4-inch open-end wrench. Using wire brush, clean wire terminal (6)
on 14-6 wire (3). Place wire terminal (6) in position and screw nut (4) and lockwasher
(5) on to terminal (7) on starter motor (8).
If 14-6 wire (3) is frayed, repair (page 2-424).
