Timing-Advance Test Procedure
This light measures advance by delaying the fl ash so that it appears to align the
crank shaft TDC mark to its pointer, and then displaying the degrees delayed.
Note that on engines with ignition contact points, dwell affects timing and must
be in calibration before timing is adjusted.
1. Connect the power leads: RED - positive, BLACK - negative. Push the
Mode Select button to select 2 or 4 stroke operation. Place the Inductive

2. Prepare the engine for timing tests, such as: warming-up, disabling electric
and vacuum control lines, and cleaning the wheel timing marks. Then run
the engine. The light should begin fl ashing.
3. Read RPM, and set the engine speed to the test specifi cation.
4. Point the light beam onto the degree marks at the engine damper wheel or
fl ywheel, and move the apparent mark to the TDC position using the Timing
Advance Control Buttons. Then read the timing advance on the display.
NOTE: Align your eye squarely with the timing marks when viewing, to
avoid parallax error.
5. Compare the measurement with the specifi cation. Adjustments are made
by turning the distributor slightly or by moving the ignition timing sensor.
6. Restore all engine parts to their normal arrangement.
