VOLTAGE TEST

T he voltage test provides a general indicator of battery
condition. Check the voltage of the battery to verify that it is
fully charged. Refer to Table 2-20.

1. If the open circuit (disconnected) voltage reading is below
12.6V:
a. Charge the battery.
b. Check the voltage after the battery has set for at least
one hour.

2. If the voltage reading is 12.7Var above:
a. Perform a battery diagnostic test. See the electrical
diagnostic manual for the load test procedure.

2. Voltage Regulator Bracket 12.7V 100%

11.8 V 0%

STORAGE

See Figure 2-44. A battery is affected by self-discharge whether
stored in or out of the vehicle. A battery that is stored in the
vehicle is also affected by parasitic loads. A parasitic load is
caused by things like diode leakage or maintaining computer
memory with the vehicle turned off.

Batteries self-discharge at a faster rate at higher ambient
temperatures. Store battery in a cool, dry place to reduce the
self-discharge rate.
1. Voltage regulator bracket
2. Starter cable Charge the battery every two weeks if stored in the vehicle.
3. Voltage regulator Charge the battery once per month if removed the vehicle.

NOTE
CLEAN AND INSPECT Use a Harley-Davidson constant monitoring battery
charger/tender to maintain battery charge for extended periods
NOTE of time without risk of overcharging or boiling.
Battery top must be clean and dry. Dirt and electrolyte on top
of the battery causes self-discharge.

1. Clean battery top.
a. Mix a solution of five teaspoons of baking soda (sodium
bicarbonate) per liter or quart of water.
b. Apply to battery top.

2. When the solution stops bubbling, rinse off battery with
clean water.
3. Clean cable connectors and battery terminals with a wire
brush or sandpaper. Remove any oxidation.
4. Inspect the battery terminal screws and cables for
breakage, loose connections and corrosion.
5. Check the battery terminals for melting or damage.
6. Inspect the battery for discoloration, raised top or a warped
or distorted case. Replace as necessary.
7. Inspect the battery case for cracks or leaks.
