Test Ignition Coil
1. Locate the connector for the ignition coil (A, Figure 56)
and disconnect..
2. Attach meter test leads to primary side of the ignition
coil and measure the resistance (B, Figure 57).
• If resistance is 0.8 - 1.3 Ω the primary coil is good.
• If resistance is not to specifications, check wire
connections, or repair/replace wires then retest.
• If resistance is still not to specification, replace the
coil.

• If 80-130 Ω resistance is measured the coil is good.
• If resistance is not to specifications, check wire
connections and retest.
• If resisitance is still not to specifications, replace
coil.
If resistance is still not to specifications, proceed to Step 3.
3. Measure the resistance between the trigger coil
(A, Figure 54) and ground.
• If 80-130 Ω resistance is measured, the coil is good.
• If resistance is not to specifications, check wire
connections and retest.
• If resisitance is still not to specification, replace coil.
