VERIFICATION OF THE DISTANCE BETWEEN
SPARK PLUG ELECTRODE
1. Check:
• Distance between electrodes of the spark plug
Out of specification Make the solution
of power system problems,
starting with step 5. See
"TROUBLESHOOTING" on page
7-3.
Minimum distance between electrodes
from 0.8 to 0.9 mm plug
NOTE:
If the distance between electrodes of the spark plug is
within specifications, the circuit
ignition system is working
normally.
a. Disconnect the spark plug cap from spark plug.
b. Connect the dynamic spark tester "1"
as shown.
