3-6 Inspecting ignition coil resistance

1. Remove cleaner lid and cylinder cover.
2. Connect one probe of Ohm-meter or multimeter
to spark plug cap coil (A).
3. Connect the other probe to cylinder fin (B) to
measure secondary coil resistance. Secondary
coil resistance should be in the range of 1.7 to 2.2
kΩ.
4. I f t h e m e t e r r e a d i n g i n d i c a t e s i n fi n i t e
r e si s ta n ce , remove spark plug cap and spark
plug cap coil, and measure resistance between the
conduction wire of high tension lead and ignition
coil core.
5. If the reading at step 2 or 3 is not in the range of
1.7 to 2.2 kΩ, replace with a new ignition coil (Go
to "3-8 Replacing ignition coil").
