Check the battery for corroded or loose
terminal connections, cracks, or loose

a. If the battery is corroded, wash it off
with a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose,
tighten their clamp nuts—but do not
overtighten.
c. Tighten the hold- down clamp
enough to keep the battery firmly in
place. Overtightening may damage the
battery case.
