4-5 Inspecting ignition module
1. Remove spark plug cap (A) from spark plug.
2. Connect black probe (b1) of Ohm-meter or mul-
timeter (B) to spark plug cap coil in spark plug cap
(A).
3. To measure secondary coil resistance, con-
tact cylinder
¿
n with red probe (b2). Secondary coil
resistance should be in the range of 960 to 1,000
ȍ
.
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

n i t e
r e s i s t a n c e , remove spark plug cap and spark
plug cap coil, and measure resistance between the
conduction wire of high tension lead and ignition
module core.
5. If the reading at step 3 or 4 is not in the range of
960 to 1,000
ȍ
, replace with a new ignition module
(Refer to “4-6 Replacing ignition module”).
