IGNITION COIL CONTINUITY
TEST
Inspect the continuity of the ignition coil,
primary coil and secondary coil.
Measure the ignition coil resistances at 20℃.
Primary coil 3.57~4.83Ω
Secondary coil with
plug cap
15 ~ 19 KΩ
Secondary coil
without plug cap
10 ~14 KΩ
This is a general test. Accurate ignition
coil test must be performed with an
ignition unit tester.
