looking at the test indicator window
on the battery. The label on the
battery explains the test indicator's
colors.
TEST INDICATOR WINDOW
6-cylinder models
Check the battery terminals for
corrosion (a white or yellowish
powder). To remove it, cover the
terminals with a solution of baking
soda and water. It will bubble up and
turn brown. When this stops, wash it
off with plain water. Dry off the
battery with a cloth or paper towel.
Coat the terminals with grease to
help prevent future corrosion.
