hold-downs) and the battery box. Replace
worn or damaged parts. Remove any
corrosion with a wire brush, and wash

prevent rusting, paint the retainer
assembly.

such as stones, bolts, or nuts, from the
battery box.
10.4 After cleaning, connect the cables to the
batteries, and tighten them to the torque
specifications listed on the battery,
generally 10 to 15 lbf·ft (14 to 20 N·m).
10.5 Coat the battery terminals with dielectric
grease.
11. Check the terminals on the battery shut-off
switch and the magnetic switch. Make sure the
terminal connections are clean and tight. Coat
the terminal connections with dielectric red
enamel after cleaning.
