Signal Coil Test

Last update: 2009-01-11

1. Resistance between the Black lead and each White lead is 200Ω

2. Resistance between the Black lead and Stator body is 0Ω

Ignition System Wiring
Check resistance between Value (limit) Circuit Function Related Malfunction
Black to stator body 0 Ω Auxiliary Ground for Ignition Signal Coils ∞ (Infinity) = Open circuit
poor performance of signal coils if stator does not ground well through engine to frame.
Black to White
(L, C, R)
200 Ω Ignition Signal Coils ∞ (Infinity) = Open circuit. engine will not run on 1,2, or 3 cylinders.
Less than 180 ͩ = Internal short. weak spark, poor performance , fouling plugs on 1, 2, or 3 cylinders
