III. Connecting the timing light
In order to ensure safety and reliable operation of the timing light, connect according to the following
steps:
Warning: keep hand, timing light, connecting wire and the signal pickup device away from the running
parts and the high temperature surface of the engine. No smoking.
3.1.
Close the ignition switch. Never connect the timing light when the engine is running or the
ignition switch is turned on.
3.2.
Clip the inductive signal pickup device to the high voltage wire of cylinder 1.(See Fig 3) Make
sure that the signal pickup device doesn't touch the discharge branch pipe or other parts of the
engine, as temperature on these parts can be very high when the engine is running, which may
damage the signal pickup device.
3.3.
Clamp the battery jar clip at the battery jar inside the vehicle.
The red clip connects the anode (+)
The black clip connects the cathode (-)

IV. Inspection of the basic ignition timing
Note: For some systems, before checking or adjusting the ignition time according to instructions,
some special elements should be unplugged, jump connected or grounded. If it's not done according
to instructions, the checked or adjusted ignition time will not be correct.
4.1.
Make sure that the timing light is correctly connected according to the above requirement.
4.2.
Make sure the preparations of the engine have been made according to the above
requirement.
4.3.
Start the engine, run to the normal working temperature.
4.4.
If needed, adjust the idle speed according to the factory's requirement.
4.5.
Observe the relative position between the timing scale and the indicator (see Fig 4): compare
the displayed timing degrees with the specified value, if the timing degrees are within the
allowed range (usually 2 degrees), then, the ignition timing is normal. If the degrees exceed the
range, it's likely that some parts need to be replaced or the timing needs to be adjusted.
