Ignition Timing
NOTE:
Self-powered timing lights may not operate with this system. Use a vehicle-battery-powered timing light for this procedure.
- Warm up engine and ensure idle speed is correct before adjustment of ignition timing. Turn all electric loads off. Connect a tachometer to engine (if necessary). Check idle speed and set to specification.
- Connect a timing light to "L-1" high-tension lead. Ensure mark on pulley and indicator pin are aligned
- Leading is 5 degrees ATDC (Yellow mark).
- Trailing is 20 degrees ATDC (Red mark).
If ignition timing is not correct, crank angle sensor must be rotated until timing marks are correctly aligned.
- To check advance, connect a timing light to "L-1" high- tension lead. Increase engine speed and ensure ignition timing advances. Disconnect timing light.
