Stick Coil Inspection
• Remove   the stick coils (see Stick Coil Removal).
•○Measure   the primary winding resistance [A] as follows.
   Connect a tester between the coil terminals.
 •○Measure the secondary winding resistance [B] as follows.
   Connect the tester between the plug terminal and (–) coil
  terminal.
  Stick Coil Winding Resistance
    Primary Windings:         1.1 ∼ 1.5 Ω
    Secondary Windings:         6.4 ∼ 9.6 kΩ
  If the tester does not read as specified, replace the coil.

Stick Coil Primary Peak Voltage Inspection
                            NOTE
  ○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 a tester [D].
○Connect the adapter to the lead wire-peak voltage
  adapter [E] which is connected between the stick coil
  connector and stick coil.
