starter. Place positive (+) probe on terminal B.
The DVOM should indicate approximately 12V.
c. Turn the key to the START position. The DVOM
will indicate “0” voltage if the starter contacts are
closed.
d. If “0” voltage is not indicated while the key is
turned to the START position, replace the starter.
VOLTAGE TEST FOR BATTERY
Hydrogen gas formed during bat-
tery charging is explosive and can
cause personal injury or death.
Avoid any electrical spark or open flame near bat-
tery.
NOTICE: If the temperature of the battery or the
ambient temperature is below 60° F (15° C), the
capacity of the battery will be less. It will require
more time to charge.
A cold battery will build up voltage and more rapidly
reduce the charging rate.
Batteries that are new or have been stored must be fully
charged before being tested or placed in vehicle.
NOTICE: Do not overcharge the battery.
Battery voltage can be checked using a voltmeter. Attach
the negative (-) lead of the DVOM to the ground terminal
of the battery. Attach the positive (+) lead to the positive
battery terminal. The voltage reading should be 12 volts
or above. If the reading is below 12 volts, the battery
requires either charging or replacement.
BATTERY
The
STAMPEDE 900
has a sealed battery, which
requires no maintenance except to keep it corrosion-free,
and to test for functionality.
The sealed battery is filled with electrolyte and sealed at
the factory. Never pry the seal strip off, or add fluid to the
battery.
Inspect the battery terminals at the intervals indicated in
the Scheduled Maintenance Chart. Clean and tighten as
needed.
Battery Cleaning
Use insulated wrenches to prevent
direct contact of a wrench with the
battery terminals. Direct contact of
a bare wrench with the battery terminals can cause
an explosion resulting in severe injury or death
Always wear eye protection when
charging the battery.
To decrease the risk of damage to electrical components
surrounding the battery while cleaning, do not use a pres-
sure washer.
1.
Remove corrosion with a wire brush.
2.
Wash with a solution of:
•
1 tsp. (5 ml) baking soda
•
1 cup (236 ml) water
3.
Rinse with tap water and dry with shop towels.
4.
After the battery is clean and dry, coat with a com-
mercially available battery terminal spray.
Battery Charging
Do not overcharge the battery.
Overcharging the battery can cause
overheating and possible explosion,
resulting in severe injury or death.
NOTICE: Use a battery charger that is designed for
charging sealed batteries.
Keep battery fully charged.
Heavy use of accessories can drain the battery and
leave insufficient charge to start the vehicle.
The sealed battery is a 12 Volt starter battery that sup-
plies power to the starter and accessories. A starter starts
the engine and an internal generator charges the battery
while the engine is running. Due to heavy use of accesso-
ries, the battery can become discharged even if the
engine is running and the generator is operating.
It is important to keep the battery fully charged. Since the
battery is sealed, a voltmeter or multimeter is required to
check voltage.
1.
Check the battery voltage with a voltmeter or multi-
meter.
•
If the voltage measured is 12.8 V or higher, the
battery is fully charged and requires no further
action.
•
If the voltage measured is less than 12.8 V,
recharge the battery.
2.
Charge the battery with a charger designed for
sealed batteries. Follow the instructions supplied
with the manufacturer of the charger.
Battery Storage
NOTICE: A battery will self-discharge over time. The
rate of discharge varies depending on ambient tem-
perature, age and condition of the battery. Check
