(b) Inspect the battery for loose posts. If slight pressure
causes the post to move, turn the battery in to intermediate support
(c) Inspect posts, clamps, and battery holddowns for corrosion.
The posts and terminals should be cleaned and coated lightly with grease. Turn
in to maintenance if:
o A post is outofround to the extent that it prevents full
contact between the post and a new clamp.
NOTE. Post and clamps are tapered for a tighter fit. Also, the positive post
is larger in diameter than the negative post.
o The post is less than 5/8 inch high. This condition would
prevent full contact between the post and a good clamp.
(2) Inspect filler caps. Check to see that the caps are not damaged
or broken and that the gasket is present. Some filler caps have a builtin
gasket made of the same material as the cap. The gasket is tapered from the
outside edge toward the center of the cap to provide a tight seal with the
case. Make sure the vent holes in the caps (Figure 22) are open to permit
escape of gases. Replace all caps that are defective.
