4. Connect RED and BLACK Battery Cli s on Negative Ground Electrical
Systems.
·Connect RED to positive (+) battery post.
·Connect BLACK to engine ground.
On 6-volt electrical systems, use an auxiliary 12-volt battery to
power timing light. Connect BLACK clip to negative (-) post and
RED clip to positive (+) post on auxiliary 12- volt battery. Use 18
AWG or larger wire to connect 12-volt battery negative (-) terminal
to a good engine ground.
On 12-volt Positive Ground electrical systems, connect BLACK clip
to negative (-) battery post and RED clip to engine ground. DO NOT
USE the positive battery post.
On engines equipped with a breaker point ignition system, it will be
necessary to set the point dwell before adjusting the timing. Always
follow the manufacturers specifications and test procedures for
adjusting dwell angle and idle speed.

5. Locate the Timing Marks on the Engine
·The Digital Timing Light is equipped with
a flashlight feature. Press and hold the
button for continuous lighting.
6. Set 2/4 CYCLE OPERATION (Digital
Timing Light Only)
·Use 2-cycle mode on 2-cycle engines and
on vehicles equipped with waste-spark
distributorless ignition systems (D S).
When connected to the battery, the timing light defaults to the 4-
cycle, tachometer mode.
·Press and release button until correct indicator lights.

MEASURING ENGINE RPM
(Digital Timing Light Only)
1. Press and Release Button Until RPM Indicator Lights.
f engine is not running or #1 spark plug is not firing, timing light
display will flash, indicating that no signal is being received.
Always follow test rocedures in vehicle service manual or Vehicle
Emission Control Information Label. Instructions given here are for
reference only.
IMPORTANT

MEASURING INITIAL TIMING
1. Follow re aration list for checking
timing in vehicle service manual.
2. Start engine and warm to o erating
tem erature.
3. Aim timing light at crankshaft
dam er ( ulley) or at transmission
bell housing, de ending on location
of timing marks.
INDUCTIVE TIMING LIGHT
1. Press and hold down button.
2. Write down initial timing by counting the timing marks
on the engine.

CHECKING & MEASURING
CENTRIFUGAL ADVANCE
INDUCTIVE TIMING LIGHT
1. Leave distributor vacuum line disconnected
and lugged.
2. Press and hold down button. Note
osition of timing mark at idle s eed.
3. Slowly increase engine s eed to 2500 RPM, or other s eed s ecified
by manufacturer. Timing mark should move smoothly in o osite
direction of engine rotation. Note degrees advance at higher RPM.
4. Subtract degrees advance at idle from degrees at higher s eed.
Difference is amount of centrifugal advance.
5. Slowly decrease engine s eed to idle RPM. Timing mark should move
smoothly in direction of engine rotation, and return to idle osition.
