4. Generator belt loose.
5. Incorrect regulator settings. These can be
corrected and set, preferably toward high limit,
as explained in Notes 40 and 42.
6. Oxidized regulator contact points.
7. Self-discharge resulting from a dirty battery
case.
8. Loose battery cable and ground strap.
9. Low generator output, which may be checked
and corrected as explained in Notes 33d and 36.
10. A partial ground in positive side of battery
circuit. With clock disconnected and all switches
in "Off" position, a milliameter or voltmeter
connected in series between positive post and
battery cable should indicate zero.
11. High resistance in charging circuits.
6. Battery Visual Inspection
1. Inspect positive cable and negative ground
cable for corrosion or damage.
2. Inspect metal carrier for corrosion. If cor-
rosion exists, it will be necessary to remove
cover and battery from car and pour warm water
over corroded areas to loosen the corrosion so
that it can be brushed off and flushed away.
3. The hold down cover should be kept tight
enough to prevent the battery from shaking in its
holder and to prevent damage to the battery case,
but should not be tightened to the point where the
battery case will be placed under a severe strain.
4. The battery posts and terminals should be in-
spected for corrosion. If corroded, wipe off the
posts and terminals with a cloth dampened with
household ammonia, or with a solution of water
and baking soda. These alkaline solutions will
neutralize any acid on parts being cleaned. Felt
washers soaked with engine oil should be installed
under each terminal to retard corrosion.
CAUTION: Care should be taken to keep
cleaning solution out of battery cells; otherwise,
the electrolyte will become permanently weak-
ened.
5. Examine battery for cracks in case, raised
cells, and also excessive tightness or looseness
in battery tray.
7. Battery Removal and Installation
a. Removal
1. Remove battery cable and ground strap.
Spread the spring type clamps with pliers and lift
them off the posts.
CAUTION: Do not spread clamps any more
than necessary. Do not pry clamps off battery
posts.
2. Remove two screws and battery hold down
cover and remove battery, being careful not to
damage posts.
b. Installation
1. Clean all corrosion from battery posts and
cable clamp terminals.
2. Install felt washers soaked with engine oil
on battery posts.
3. Install battery in car and connect battery
cable and ground strap. Spread clamps with pliers
and push them onto the battery post as far as
possible. When installed, the clamps should be
from flush with the top of the post to approximately
1/8 inch below the top, Fig. 12-6.
CAUTION: Do not drive clamps onto battery
posts with hammer or other tool. The spring
ring inside the clamp should never be reamed
or cut as this will damage it.
4. Install battery hold down cover, securing with
two screws. Avoid over-tightening screws.
