ELECTRICAL SYSTEM 16-43
Ignition System
Stick Coil (Ignition Coil together with Spark Plug Cap)
Inspection
•
Remove the stick coils (see this chapter).
•
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 (–) c oil
terminal.
○
Set the tester to the × 1 kΩ range and read the tester.
Ignition Coil Winding Resistance
Primary Windings: 1.04 ∼ 1.56 Ω
Secondary Windings: 10.8 ∼ 16.2 kΩ
If the tester does not read as specified, replace the coil.
Stick Coil Primary Peak Voltage
NOTE
○
Be sure the battery is fully charged.
•
Remove the stick coils (see this chapter), but do not re-
move the spark plugs.
•
Measure the primary peak voltage as follows.
○
Connect a commercially peak voltage adapter [B] into the
hand tester [C] which is set to the x 250 V DC range.
○
Connect the adapter to the l ead wire-peak voltage
adapter [A] which is connected between the stick coil
connector and stick coil.
○
Install the new spark plug [D] into each stick coil [E], and
ground them onto the engine.
