wire brush and a sodium bicarbonate (baking soda)
and warm water cleaning solution. Paint any exposed
bare metal and replace any damaged parts.
(6) Inspect the battery case for cracks or other
damage that could result in electrolyte leaks. Also,
check the battery terminal posts for looseness. Bat-
teries with damaged cases or loose posts must be
replaced.
(7) Check the electrolyte level in the battery. Use a
putty knife or another suitable wide flat-bladed tool
to pry the cell caps off (Fig. 19). Do not use a screw-
