MAINTENANCE
Battery
Battery Charging (Conventional Battery)
1. Remove the battery from the vehicle to prevent damage from leak-
ing or spilled electrolyte during charging. See page 105.
2. Charge the battery with a charging output no larger than 1/10 of the
battery's amp/hr rating. Charge as needed to raise the specific grav-
ity to 1.270 or greater.
3. Reinstall the battery. See page 106. Make sure the positive terminal
is toward the front of the vehicle.
Battery Charging (Sealed Battery)
The following battery charging instructions apply only to the installa-
tion of a sealed battery. Read all instructions before proceeding with the
installation of this battery.
The sealed battery is already filled with electrolyte and has been sealed
and fully charged at the factory or dealership. Never pry the sealing strip
off or add any other fluid to this battery.
The single most important thing about maintaining a sealed battery is to
keep it fully charged. Since the battery is sealed and the sealing strip
cannot be removed, you must use a voltmeter or multimeter to measure
DC voltage.
An overheated battery may explode, causing severe injury or death. Always
watch charging times carefully. Stop charging if the battery becomes very
warm to the touch. Allow it to cool before resuming charging.
For a refresh charge, follow all instructions carefully.
1. Check the battery voltage with a voltmeter or multimeter. A fully
charged battery will register 12.8 V or higher.
2. If the voltage is less than 12.8 volts, recharge the battery at 1.2 amps
or less until battery voltage is 12.8 or greater.
NOTE:
For convenience, a charging harness has been routed from the battery
to the area near the radiator filler cap. Open the front storage box
cover to access the harness.
