APPLICATIONS

This timing light is designed for use on most late model import or domestic vehicles equipped with
conventional or electronic ignition systems, or with DIS (distributorless ignition systems).

TIMING LIGHT CONNECTION

WARNING: Always keep hands, timing light, lead wires and clips away from moving engine
parts and hot surfaces. DO NOT SMOKE.
a. Turn ignition off. DO NOT CONNECT TIMING LIGHT WITH IGNITION ON OR ENGINE
RUNNING.
b. Clamp inductive pickup clip around No. 1 spark plug wire (arrow points toward spark plug).
c. Connect the green DWELL clip to the negative (tach) side of the ignition coil (if applicable).
d. Connect battery clips to battery:
■
Connect RED clip to battery positive (+) terminal.
■
Connect BLACK clip to battery negative (-) terminal or chassis ground.
e. Attach pickup leads into bottom of timing light handle.

VOLTMETER OPERATION

•
Make sure timing light is properly connected as described in TIMING LIGHT CONNECTION.
•
ALWAYS check battery and charging system voltage before performing timing check to ensure
reliable results.
a. With timing light connected and engine off, timing light is in battery voltage mode; the Battery
VOLTS indicator, Volts symbol and Battery symbol will display. The LCD display will show
battery voltage.
b. When the engine is started, the timing light enters the voltage/rpm mode; the Charging System
Battery VOLTS indicator, Volts symbol and Ignition Mode symbol (either 2-cycle (DIS) or 4-
cycle) will display. The LCD display will show charging system voltage and engine rpm.

CHECKING DWELL ANGLE

Dwell angle check is performed for vehicles equipped with conventional or electronic ignition systems.
•
Make sure timing light is properly connected as described in TIMING LIGHT CONNECTION.
a. Start and run engine until it reaches normal operating temperature.
b. Press Function (F) switch as needed to select dwell mode. The DWELL Indicator, Cylinder
Symbol, and Dwell Angle Symbol will display when dwell mode is selected.
■
Press Cylinder/Advance Increment and Decrement switches as needed to select
appropriate number of cylinders for vehicle under test. The LCD display will show the
number of cylinders selected and the dwell angle.
c. Note dwell angle and compare to manufacturer's specifications.
d. Refer to the vehicle's service manual for procedures to adjust dwell angle.
e. Turn ignition off and disconnect timing light from engine.
