BATTERY RECHARGING
There are two separate methods of recharging batter-
ies which basically in the rate of charge. In the
slow-charge method, the battery is supplied a rela-
tively small amount of current for an extended
period of time. In the quick-charge method, the bat-
tery is supplied with a high current for a short period
of time.
Slow-Charging
Slow
is the best and only method of com-
pletely a battery. The slow-charge method,
properly applied, may be safely used under all possi-
ble conditions of the battery, provided electrolyte is
at proper in all cells. The battery may be fully
charged by this method, unless the battery is not
capable of taking a full charge. The normal slow
charging rate for the battery is 5 amperes.
Full of battery is indicated when cell
gravities do not increase when checked at three
intervals one hour and cells are gassing freely.
Due to low rate during slow charging, plenty of
time must allowed. Charge periods of 24 hours or
more are often required.
Quick-Charging
Since often of most importance to the battery
owner, quick-charging must sometimes be used to
partially charge the battery so that the engine will
start
and the owner can be on
his way.
Charge amperes for 20 minutes (50 times 20
equals ampere minutes). If charger will not give
this rate, charge for an equal number of ampere mi-
nutes at the best rate available. Too high a current
during quick-charging will damage battery plates.
A battery cannot be brought up to a fully charged
condition
the quick-charge method. The battery
can be substantially recharged or boosted, but in
order to bring the battery to a fully charged condi-
tion, the charging cycle must be finished by charging
at a low normal rate. Some quick-chargers have
a for finishing the charging cycle at a low
rate so the battery can be brought up to a fully
charged condition.
Used and employing all safeguards prov-
ided by the manufacturer, a quick-charger will not
damage a battery which is in good condition.
BATTERY REMOVAL AND INSTALLATION
Removal
1. Disconnect battery cables (remove negative cable
to prevent possible shorting).
2. Remove battery hold down
3. Remove battery.
Installation
Place battery back in hold down position.
2. Tighten hold down bracket bolts.
3. Connect battery cables (connect positive cable first
to prevent possible shorting).
FUSIBLE LINK REMOVAL AND INSTALLATION
Replace a burned out fusible link as follows:
1. Disconnect battery.
2. Disconnect connector eye on end of fusible link.
3. Cut off other end of burned out link, along with
solder joint.
4. Strip insulation from end of new fusible link and
from end of wiring harness so that each will slide
soldering sleeve.
5. Crimp new link in soldering sleeve and solder
carefully.
6. Cover new connection tightly with electrical tape.
Install new link connector eye on other end of
fusible link.
A burned out fusible link connected to the starter
solenoid would be indicated by:
1. All electrical accessories dead.
2. Starter dead will not even click. Even with a
nearly dead battery, the starter solenoid will
ally engage; therefore, no click means no solenoid
action, possibly due to a burned out fusible link.
