Stick Coil Inspection
Remove the stick coils (see Stick Coil Removal).
Measure the primary winding resistance [A] as follows.
Connect the hand tester between the coil terminals.
Set the tester to the × 1 Ω range, and read the tester.
Measure the secondary winding resistance [B] as follows.
Connect the tester between the plug terminal and (–) coil
Set the tester to the × 1 kΩ range and read the tester.
Stick Coil Winding Resistance
If the tester does not read as specified, replace the coil.
Stick Coil Primary Peak Voltage
Be sure the battery is fully charged.
Remove the stick coils (see Stick Coil Removal), but do
not remove the spark plugs.
Measure the primary peak voltage as follows.
Install the new spark plug [A] into each stick coil [B], and
ground them onto the engine.
Connect the peak voltage adapter [C] into the hand tester
[D] which is set to the DC 250 V range.
Connect the adapter to the lead wire-peak voltage
adapter [E] which is connected between the stick coil
connector and stick coil.
