CLEANING

Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)

If the plugs require cleaning between tune-ups:

Clean electrodes and insulator with electrical contact
cleaner. Dry plug with compressed air.

Use a thin file to flatten electrodes.

NOTE

Electrodes with sharp edges require 25-40 percent less voltage
than ones with rounded edges.

Check condition of threads in cylinder head. Use a penet-
rating oil and clean out with a thread chaser. Verify that
plug threads are clean.

If necessary, replace with

new

spark plugs.

BATTERY MAINTENANCE

GENERAL

Batteries contain sulfuric acid, which could cause severe
burns to eyes and skin. Wear a protective face shield,
rubberized gloves and protective clothing when working
with batteries. KEEP BATTERIES AWAY FROM CHILDREN.
(00063a)

Never remove warning label attached to top of battery.
Failure to read and understand all precautions contained
in warning, could result in death or serious injury. (00064a)

Batteries, battery posts, terminals and related accessories
contain lead and lead compounds, and other chemicals
known to the State of California to cause cancer, and birth
defects or other reproductive harm. Wash hands after
handling. (00019e)

Keep battery clean and lightly coat terminals with petro-
leum jelly to prevent corrosion. Failure to do so could
result in damage to battery terminals. (00217a)

AGM batteries are permanently sealed, maintenance-free,
valve-regulated, lead/calcium and sulfuric acid batteries. The
batteries are shipped pre-charged and ready to be put into
service. Do not attempt to open these batteries for any reason.

CLEANING AND INSPECTION

NOTE

Battery top must be clean and dry. Dirt and electrolyte on top
of the battery causes battery to self-discharge.

Clean battery top with a solution of baking soda (sodium
bicarbonate) and water (5 teaspoons baking soda per
quart or liter of water).

When the solution stops bubbling, rinse off the battery with
clean water.

Clean cable connectors and battery terminals using a wire
brush or sandpaper. Remove any oxidation.

Inspect the battery screws, and cables for breakage, loose
connections and corrosion.

Check the battery terminals for melting or damage caused
by over-tightening.

Inspect the battery for discoloration, raised top or a warped
or distorted case. This might indicate that the battery has
been frozen, overheated or overcharged.

Inspect the battery case for cracks or leaks.

VOLTMETER TEST

Never remove warning label attached to top of battery.
Failure to read and understand all precautions contained
in warning, could result in death or serious injury. (00064a)

Voltmeter Test

The voltmeter test provides a general indicator of battery con-
dition. Check the voltage of the battery to verify that it is fully
charged.

If the open circuit (disconnected) voltage reading is below
12.6 V:

Charge the battery.

Check the voltage after the battery has set for at least
one hour.

If the voltage reading is 12.7 V or above:

Perform a battery diagnostic test. See the electrical
diagnostic manual for the load test procedure.

CHARGING BATTERY

Safety Precautions

An automatic, constant monitoring battery charger/tender with
a charging rate of 5 amps or less at less than 14.6 volts is
recommended. The use of constant current chargers (including
trickle chargers) to charge sealed AGM batteries is not
recommended.

Any overcharge will cause dry-out and premature battery
failure. Always review charger instructions before charging a
battery. In addition to the manufacturer's instructions, follow
these general safety precautions:

•

Always wear eye, face and hand protection.

•

Always charge batteries in a well-ventilated area.

•

Turn the charger off before connecting or disconnecting
the leads to the battery to avoid dangerous sparks.

•

Never try to charge a visibly damaged or frozen battery.

•

Connect the charger leads to the battery. Red positive
lead to the positive terminal. Black negative lead to the
negative terminal. If the battery is still in the vehicle, con-
nect the negative lead to the chassis ground. Verify that
the ignition and all electrical accessories are turned off.

•

Verify that charger leads to battery are not separated,
frayed or loose.

•

If the battery temperature exceeds 110 °F (43 °C) during
charging, discontinue charger and allow the battery to
cool.

Using a Battery Charger

Charge the battery if:

•

Vehicle lights appear dim.

•

Electric starter sounds weak.

•

Battery has not been used for an extended period of time.

Explosive hydrogen gas, which escapes during charging,
could cause death or serious injury. Charge battery in a
well-ventilated area. Keep open flames, electrical sparks
and smoking materials away from battery at all times.
KEEP BATTERIES AWAY FROM CHILDREN. (00065a)

HOME

1-52 2013 Softail Service: Maintenance

If battery releases an excessive amount of gas during
charging, decrease the charging rate. Overheating can
result in plate distortion, internal shorting, drying out or
damage. (00413b)

Check charge state with voltmeter test. If battery voltage
is less than 12.7 volts, see the next step.

NOTES

•

Most constant monitoring battery chargers are completely
automatic. They can be left connected to both AC power
and to the battery that is being charged. When leaving this
type of charger connected for extended periods of time,
periodically check the battery to see if it is unusually warm.
This is an indication that the battery may have a weak cell
or internal short. Read the manufacturer's instructions for
the charger.

•

Do not use battery chargers that produce excessively high
voltage designed for flooded batteries or excessively high
current designed for much larger batteries. Charging
should be limited to 5 amps maximum at no more than
14.6 volts.

Unplug or turn OFF battery charger before connecting
charger cables to battery. Connecting cables with charger
ON can cause a spark and battery explosion, which could
result in death or serious injury. (00066a)

Do not reverse the charger connections described in the
following steps or the charging system of the motorcycle
could be damaged. (00214a)

Connect red battery charger lead to the positive terminal
and black battery charger lead to the negative terminal of
the battery.

NOTE

If the battery is still in the vehicle, connect the negative lead
to the chassis ground. Be sure that the ignition and all electrical
accessories are turned off.

Step away from the battery and turn on the charger.

Unplug or turn OFF battery charger before disconnecting
charger cables from battery. Disconnecting clamps with
charger ON can cause a spark and battery explosion, which
could result in death or serious injury. (00067a)

After the battery is fully charged, turn the charger OFF.
Disconnect the black battery charger lead to the negative
terminal of the battery.

Disconnect the red battery charger lead to the positive
terminal of the battery.

Mark the charging date on the battery.

Perform a battery diagnostic test to determine the condition
of the battery. See the electrical diagnostic manual.

If charging a battery because voltmeter test reading was
below 12.6 V, perform voltmeter test. See the electrical
diagnostic manual.

DISCONNECTION AND REMOVAL

Disconnect negative (-) battery cable first. If positive (+)
cable should contact ground with negative (-) cable con-
nected, the resulting sparks can cause a battery explosion,
which could result in death or serious injury. (00049a)

Remove the seat.

See

Figure 1-49

charger/tender to maintain battery charge. Refer to the Harley-
Davidson Parts and Accessories catalog.

If the motorcycle is stored with the battery installed, without a
GLOBAL BATTERY CHARGER, and with the security system

not

armed, remove main fuse.

If the motorcycle will not be operated for several weeks, such
as during the winter season, remove the battery from the
motorcycle and fully charge.

See

Figure 1-50

. A battery that is removed from the vehicle is

affected by self-discharge. A battery that is stored in the vehicle
is affected by self-discharge and, more significantly, 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. To reduce the self-discharge rate, store battery
in a cool, dry place.

Charge the battery every two weeks if stored in the vehicle.
Charge the battery once per month if stored out of the vehicle.

NOTE

Use the GLOBAL BATTERY CHARGER (Part No. 99863-01A)
to maintain battery charge for extended periods of time without
risk of overcharging or boiling.

HEADLAMP ALIGNMENT

The automatic-on headlamp feature provides increased
visibility of the rider to other motorists. Be sure headlamp
is on at all times. Poor visibility of rider to other motorists
can result in death or serious injury. (00030b)

NOTE

Adjust the headlamps of motorcycles with multiple beam
headlamps to converge into one pattern.

Check the tire pressure.

Adjust the rear shocks for the rider and intended load.

Fill fuel tank or add an equal amount of ballast.

NOTE

Choose a wall in minimum light.

See

Figure 1-55

. Park the motorcycle in a line (1) perpen-

dicular to the wall.

Position motorcycle so that front axle is 25 ft (7.6 m) from
wall.

Draw a vertical line (2) on the wall.

With the motorcycle loaded, point the front wheel straight
forward at wall. Measure the distance (4) from the floor to
the center of the high beam bulb.

Draw a horizontal line (5) through the vertical line on the
wall. Place line 2.1 in (53.3 mm) lower than the measured
bulb centerline.

NOTE

See

Figure 1-55

. The headlamp is aligned when the light beam

hot spot is located over the intersection of the lines.

With the high beam activated, verify headlamp alignment.
Adjust as necessary.
