Electrical Connections

The electrical connections should be checked periodi-
cally for proper function. In case of an electrical failure,
check fuses, connections (for tightness, corrosion, dam-
age), and/or bulbs.
After being in service, batteries require regular cleaning
and recharging in order to deliver peak performance and
maximum service life. The following procedure is rec-
ommended for cleaning and maintaining sealed batteries.
Always read and follow instructions provided with bat-
tery chargers and battery products.
Any time service is performed on a battery, the follow-
ing must be observed: keep sparks, open flame, ciga-
p/n
rettes, or any other flame away. Always wear safety
0644-191
glasses. Protect skin and clothing when handling a bat-
0644-559 tery. When servicing battery in enclosed space, keep
0744-041 the area well-ventilated. Make sure battery venting is
not obstructed.
1. Remove the battery case access cover; then discon-
nect the battery cables (negative cable first).
2. Remove the battery from the battery case; then thor-
oughly wash the battery and battery case with soap
and water.
 NOTE: If battery posts, cable ends, or the battery
case has a build-up of white/green powder residue,
apply water and baking soda to neutralize acid; then
flush off with warm soapy water.
3. Using a wire brush, clean the battery posts and cable
ends removing all corrosive buildup. Replace dam-
aged cables or cable ends.
Battery acid is harmful if it contacts eyes, skin, or cloth-
ing. Care must be taken whenever handling a battery.
4. Using a multimeter, test the battery voltage. The
meter must read 12.5 or more DC Volts for a fully
charged battery.
 NOTE: At this point, if the meter reads as specified,
the battery may be returned to service (see step 8).
5. If the meter reads less than specified voltage, charge
the battery using the following guidelines.
A. When using an automatic battery charger, always
follow the charger manufacturer's instructions.
B. When using a constant-current battery charger,
use the following Battery Charging Chart.
Never exceed the standard charging rate.
An overheated battery could explode causing severe
injury or death. Always monitor charging times and
charge rates carefully. Stop charging if the battery
becomes very warm to the touch. Allow it to cool before
resuming charging.
