4.2.1.6. Press the On/Off switch (fig.1.4) to turn on the timing light. Note that on TL2000 the ‘On’ indicator (fig.1.5) will blink to show that light is on.
4.2.1.7. TL2000 - Check that advance display (fig.1.6) reads 0
TL2001 - Check that advance dial (fig.1.8) reads 0
4.2.1.8. Illuminate timing marks with timing light. Note position of timing marks in relation to reference mark or pointer.
4.2.1.9. If timing mark alignment does not correspond with vehicle specification refer to manufacturer’s instructions for details of adjustment
and/or component replacement.
4.2.2. Advance
4.2.2.1. Having determined and noted basic timing, check advance as follows.
4.2.2.2. Illuminate timing marks with timing light and gradually increase engine speed to the figure specified by manufacturer for advance control
test. Watch movement of timing marks relative to reference mark/pointer as speed increases. Movement should be smooth. No
movement, or jerky movement, indicates faulty advance control.
4.2.2.3. When test speed is reached adjust timing light,TL2000 - by pressing advance increase/decrease buttons (fig.1.9/10), TL2001- by turning
advance dial (fig.1.8), until timing mark appears to be in the basic timing position as determined in para.4.2.1.
4.2.2.4. The reading, digital on TL2000, dial on TL2001, is the ignition advance at that engine speed. Compare with manufacturer’s specification.
Note: The above procedure, in conjunction with the manufacturer’s instructions, can be used for checking mechanical advance and vacuum
and electronic advance and retard.
4.2.2.5. When advance check is completed switch off ignition and then disconnect timing light. DO NOT disconnect with engine running.

TROUBLESHOOTING
THE PROBLEM
THE CAUSE
Timing light fails
1) Poor connection
to operate or
2) Cross-connected clamps on battery terminals
operates
3) Inductive pick-up dirty
erratically.
4) Faulty No.1 spark plug or HT lead
5) Low HT voltage
Note: Some ignition systems and/or plug leads radiate above normal electromagnetic and radio frequency fields which can cause
improper operation of timing light (this equipment will normally only be found on vehicles not intended for road use). Contact the
manufacturers of such equipment for instructions on how to use the inductive pick-up with their components.
