The Indian Chief Vintage motorcycle is equipped with
an electronically controlled ignition system. As such,
timing is programmed into the ignition module and does
not require the static and dynamic adjustments required
in past models. However, the following

This test is used to determine if the sensor within the
ignition cover is functioning without removing the cover
from the motorcycle.
Check to make sure that both the ignition key and the
engine stop switches are in the OFF position.
Disconnect the ignition cover (trigger plate) harness
connector. This is the triangular-shaped, three-pin
connector located between the frame rails under the
engine.
Connect the trigger plate and speedometer sensor tester,
98-056, to the connector from the ignition cover, using
the adapter harness supplied with the tester.
Figure 7 — Trigger plate test connection
Note:
Check to make sure that the location of the
colored wire leads in the adapter harness connector
correspond with the color indicators on the tester
module. If not, change the wire locations in the adapter
harness to match up with the tester.
Turn the tester’s power switch on. The power indicator
light should be brightly lit. If not, replace the battery in
the tester.
With the transmission in neutral, turn both the ignition
key switch to the ON position and engine start switch to
the RUN position.
Depress the start switch and observe the tester’s
SENSOR indicator light as the engine turns over.
•
Indicator light cycles on and off
— The sensor
in the ignition cover is OK.
•
Indicator light does not cycle on and off
— The
sensor in the ignition cover is malfunctioning or
there is a problem with the ignition rotor. Replace
the cover or rotor as necessary.
Disconnect and remove the tester from the ignition
cover connector.
Connect the ignition cover (trigger plate) three-pin
terminal to the chassis harness connector.

This test is used to determine if the speed sensor is
functioning without removing the sensor from the
motorcycle.
Check to make sure that both the ignition key and the
engine stop switches are in the OFF position.
Connect the trigger plate and speedometer sensor tester,
98-056, to the connector from the speed sensor, using
the adapter harness supplied with the tester. This is the
flat-shaped, three-pin connector located at the right side
of the transmission near the rear frame stanchion.
Note:
Check to make sure that the location of the
colored wire leads in the adapter harness connector
correspond with the color indicators on the tester
module. If not, change the wire locations in the adapter
harness to match up with the tester.
Turn the tester’s power switch on. The power indicator
light should be brightly lit. If not, replace the battery in
the tester. The SENSOR indicator may also be lit
depending on the position of the sensor gear.
