Indian motorcycle 2017. Service Manual - page 34

Batteries produce explosive gases. Keep sparks,
flame, cigarettes, etc. away. Ventilate when
charging or using in an enclosed space. Always
shield eyes when working near batteries.

KEEP BATTERIES AND BATTERY ACID OUT OF
REACH OF CHILDREN

The charging system used on the motorcycle is

calibrated for the maintenance free battery that is

installed as original equipment. Do not replace with a

conventional lead-acid battery. Before

troubleshooting the charging system, inspect the

battery thoroughly. A discharged, poorly charged or

faulty battery will make the readings obtained

during charging system troubleshooting erroneous

or difficult to interpret.

A battery will self-discharge when the motorcycle is

not in use. Make sure to properly store the battery as

outlined later in this section.

Maximum voltage and service life is only achieved

when the battery is properly serviced initially. Make

sure to follow instructions outlined later in this

section.

Overcharging can be caused by a faulty battery

(shorted cell). Test system with a known good

battery when diagnosing an overcharge condition.

New batteries must be properly maintained as

outlined in this section to ensure proper service life.

CAUTION

Even with a good battery, battery voltage can

recover after charging, but under excessive loads the

battery voltage will drop quickly and eventually

“die”. Often the charging system is suspect when it is

not the cause of the problem. Always inspect for

excessive loads if the battery continues to lose its

charge. Items such as incorrect wattage bulbs,

sticking brake light switch(s), continuous low rpm

operation or leaving the lights on without the engine

running for long periods of time can drain a battery

even if the charging system is operating correctly.

CAUTION

WIRE ROUTING

Make sure that all wires are routed correctly away

from moving parts, hot exhaust, or sharp edges.

CAUTION

FUSES

Fuses are in place to protect circuit wiring and

components. Always determine the cause of an open

fuse before installing a new fuse.

Do not increase the value of the fuse to correct the

problem.

Do not use wire, tin foil or other substitutes for fuses.

CAUTION

ELECTRONIC COMPONENTS

Semiconductor parts used in electronic components

will not withstand careless handling.

Do not drop or strike parts that contain

semiconductors such as the ECM or rectifier/

regulator. Dropping electronic components can

cause damage to the component.

Follow instructions supplied in this chapter, including

Fuel Delivery / EFI chapter and Electrical chapter,

very carefully when working on electronic

components. Failure to follow instructions may cause

irreparable damage to the part being inspected.

Inspect for cracked or broken battery case.

CAUTION

Do not remove the battery cap assembly in an

attempt to inspect fluid level, specific gravity or

attempt to add fluid to battery. After initial servicing,

battery should remain sealed.

Inspect terminals for corrosion. If corrosion is
found, remove battery and clean terminals with a
solution of baking soda and water. Finish process
by cleaning terminals (both battery and battery
cables) with a wire brush.

The recommended battery tester for all Indian
Motorcycle batteries is special tool

PU-50296.

See

Special Tools Index, page 1.50.

Conductance describes the ability of a battery to
conduct current. A conductance tester functions by
sending a low frequency AC signal through the battery
and a portion of the current response is captured, from
this output a conductance measurement is calculated.
Conductance testing is more accurate than voltage,
specific gravity, or load testing.
