GENERAL INFORMATION
The ignition switch is mounted on the steering
column and is connected to the key lock
assembly by a remote lock rod.
IGNITION SWITCH REMOVAL
Remove the lower instrument panel trim panel.
Place the key lock in the O F F - LOCK position.
Remove the two ignition switch attaching
screws.
Disconnect the ignition switch from the remote
rod.
Disconnect the black harness connector.
Disconnect the white harness connector.
Remove the ignition switch from the steering
column.
IGNITION SWITCH TESTING
To test the ignition switch circuitry and
continuity, place the slide bar in the position to
be tested and use either an ohmmeter or
Continuity Light J-21008, or equivalent.
Ignition Switch Positions
Starting from the alignment hole end of the
ignition switch, the switch positions are:
• A C C E S S O R Y
• O F F - LOCK
• O F F
• ON and START.
Each position has a detent stop except S T A R T
which is spring loaded to released.
Electrical Resistance
No electrical resistance should be indicated
(test lamp ON) between two c o n n e c t e d
terminals.
Maiimum Voltage Drop
The maximum voltage drop between any two
connected terminals should not exceed 12.5
millivolts per amp.
For example: if a 10-amp load is drawn through
the switch, the maximum voltage drop should be
10 x 0.0125 or 0.125 volt.
The ignition switch slide bar positions can be
easily identified by first locating the alignment
hole which is found in the flat portion of the
ignition switch adjacent to the terminals.
