16-24 ELECTRICAL SYSTEM
Ignition System
Ignition Coil Installation
Install:
Tube [A] (for rear ignition coil wire)
Ignition Coil Inspection
Measure the ignition coil [C] resistance.
Measure primary winding resistance [A]
Measure secondary winding resistance [B]
Ignition Coil Winding Resistance
Primary Winding: 1.9 2.5
Secondary Winding: 10 16 k
If the meter does not read as specified, replace the coil.
If the meter reads as specified, the ignition coil windings
are probably good. However, if the ignition system still
does not perform as it should after all other components
have been checked, test replace the coil with one known
to be good.
Check the spark plug lead for visible damage.
If the spark plug lead is damaged, replace the coil.
Ignition Coil Primary Peak Voltage Inspection
NOTE
Be sure the battery is fully charged.
Remove the spark plug cap, but do not remove the spark
plug.
Measure the primary peak voltage as follows.
Connect the peak voltage adapter [A] to the hand tester
[B] (250 V DC range), and install the needle adapter set
[C] on the peak voltage adapter lead.
Special Tools - Hand Tester: 57001-1394
Needle Adapter Set: 57001-1457
Peak Voltage Adapter: 57001-1415
Type: KEK-54-9-B
Insert the needle adapter inside the seal until the needle
reaches the terminal in the connector [D].
Install a new spark plug [E] into the spark plug cap, and
ground it to the engine.
[F] Ignition Coil
[G] Igniter
[H] Battery
WARNING
To avoid extremely high voltage shocks, do not
touch the spark plugs or tester connections.
