Note. Be sure the battery is fully charged.
Remove the stick coils (see this chapter), but do not remove the spark plugs.
Measure the primary peak voltage as follows.
Install the new spark plug [E] into each stick coil [D], and ground them onto the engine.
Connect a commercially peak voltage adapter [B] into the hand tester [A] which is set to the x 250 V DC range.
Connect the adapter to the lead wire-peak voltage adapter [C] which is connected between the stick coil connector and stick coil.

Recommended Tool - Peak Voltage Adapter; Type: KEK-54-9-B; Brand: KOWA SEIKI
Special Tools:
Hand Tester: 57001-1394
Lead Wire-Peak Voltage Adapter: 57001-1449
Primary lead connection:
Adapter (R, +) to lead wire-peak voltage adapter (W)
Adapter (BK, -) to lead wire-peak voltage adapter (R)
Warning! To avoid extremely high voltage shocks, do not touch the spark plugs or tester connections.
Turn the ignition switch and the engine stop switch ON.
Pushing the starter button, turn the engine 4-5 seconds with the transmission in neutral to measure the primary peak voltage.
Repeat the measurements 5 times for one stick coil.
Stick coil primary peak voltage. Standard: 92 V or more
Repeat the test for the other stick coil.
★ If the reading is less than the specified value, check the following.
