Battery Charging Procedure
Charge the battery using a charger capable of producing voltage
1/10th of the battery’s amp/hr rating.
Example: Youth batteries
have an amp/hr rating of 12 amps. Do not exceed 1.2 amps
charging voltage or damage to the battery will result.
Fully charged, the battery should read 12.8-13.0 Volts . After
charging is complete, let the battery stand 1-2 hours and re-test
the voltage.
Do not overcharge the battery!
There is no need to remove the cell cap strip or add water for the
life of the battery.
Because of the characteristics of a sealed battery, overcharging
decreases the volume of electrolyte. The longer the overcharge
time, the greater the drop in electrolyte, and subsequently
starting power. Water cannot be added to a sealed battery.
If a
sealed battery is overcharged, it will have to self-discharge
before it can be used.
Overcharging can also warp plates,
making future charging difficult. Watch charging times
carefully, or use a charger with limited charging time/current
capabilities. Polaris recommends using the Christie Multi
Battery Charger
(PV-67030) , available from tool provider SPX
for charging batteries. Always stop charging if the battery
becomes warm to the touch. Let it cool sufficiently before
resuming charging.
Battery Storage
Whenever the vehicle is not used for a period of three months or
more, remove the battery from the vehicle, ensure that it's fully
charged, and store it out of the sun in a cool, dry place. Check
battery voltage each month during storage and recharge as
needed to maintain a full charge.
STARTER SYSTEM
Starter Relay
The starter relay consists of a simple 2-way circuit. Power is
present at the (RD) wire from the battery. Once the switching
side of the relay receives power from the brake switch and a
ground path when the key is turned to the START position,
battery power is sent to the starter motor to crank the engine.
The relay assembly is attached to a cross member located above
the engine.
Use the illustration below when troubleshooting a “No Start”
condition.
