2. Connect the tachometer and stroboscope. Connect the tachometer tester probe to the "IG" (-) terminal of the diagnostic connector.
Note:
- Never allow the tachometer lead to touch ground as this may cause damage to the commutator and/or ignition coil.
- Some tachometers are not compatible with this ignition system, so check the compatibility of your unit before use.
3. Adjust the ignition timing.
a) Using a jumper, short-circuit the terminals "TE1" and "E1" of the diagnostic connector.
b) Bring the engine to a speed of 1000-1500 rpm and hold it at this speed for 5 seconds, then make sure that after releasing the throttle valve it returns to normal idle speed
c) Using a stroboscope, check the ignition timing angle.
Ignition advance angle at idle speed - 10° before TDC (with shorted diagnostic terminals and automatic transmission selector in position "N")
d) If necessary, loosen the two bolts and adjust the ignition timing by turning the distributor housing.
d) Tighten the two bolts and recheck the ignition timing.
Tightening torque - 20 Nm
e) Remove the jumper from the diagnostic connector.
4. Recheck the ignition timing angle.
Ignition advance angle at idle speed - 10-20° before TDC
Note: The timing mark on the crankshaft pulley moves within the range between the values specified for each engine.
5. Remove the tachometer and stroboscope.
