1996 SUBARU LEGACY charging

CAUTION:

Observe the items in 1. NORMAL CHARGING 6-2
[W2C1].

Never use more than 10 amperes when charging the
battery because that will shorten battery life.
3. JUDGMENT OF BATTERY IN CHARGED
CONDITION
1) Specific gravity of electrolyte is held at a specific value
in a range from 1.250 to 1.290 for more than one hour.
2) Voltage per battery cell is held at a specific value in a
range from 2.5 to 2.8 volts for more than one hour.
4. CHECK HYDROMETER FOR STATE OF CHARGE
Hydrometer indicator State of charge Required action
Green dot Above 65% Load test
Dark dot Below 65% Charge battery
Clear dot Low electrolyteReplace battery.* (If
cranking complaint)
*: Check electrical system before replacement.

3. Ignition Switch
A: REMOVAL AND INSTALLATION
1. IGNITION SWITCH
1) Remove screws, separate upper column cover and
lower column cover.
2) Remove instrument panel lower cover.
B6M0333
3) Disconnect ignition switch connector from body har-
ness.
4) Using a drift and hammer, hit the torn bolt head to
loosen and remove the ignition switch.

1. General Description
1. HOW TO USE THIS MANUAL
The description of the electrical system is divided into the
charging system, starting system, etc.
1) First, open to the necessary electrical system section
and wiring diagram.
2) Next, open the foldout page of the electrical wiring dia-
gram. By observing the electrical wiring harness’ illustra-
tions (front, instrument panel, etc.), the wiring diagram con-
nector can be located.

2. WIRING DIAGRAM
The wiring diagram of each system is illustrated so that you
can understand the path through which the electric current
flows from the battery.
Sketches and codes are used in the diagrams. They should
read as follows:
1) Each connector and its terminal position are indicated
by a sketch of the connector in a disconnected state which
is viewed from the front, as shown in figure.
