6-30 ELECTRICAL SYSTEM
Measure ignition coil primary peak voltage (for #2 and #3
cylinders) in the same manner as for cylinders #1 and #4.
Ignition coil (for #2 and #3 cylinders):
B/Y terminal (+ Probe) – Ground (- Probe)
B/Y: Black with Yellow tracer
NOTE:
Do not disconnect the ignition coil primary wire.
' Tester knob indication: Voltage (&
$ Ignition coil primary peak voltage: More than 140 V
If the voltages are lower than the standard values, inspect the
ignition coil and the signal generator.
IGNITION COIL RESISTANCE
• Measure the ignition coil resistance in both the primary and
secondary windings. If the windings are in sound condition, their
resistance should be close to the specified values.
0 Tester knob indication: Resistance (Ω Ω Ω Ω Ω )/(kΩ Ω Ω Ω Ω )
$ Ignition coil resistance
Primary: Approx. 2 – 4 Ω Ω Ω Ω Ω ( + tap – - - - - - tap)
Secondary: Approx. 30 – 40 kΩ Ω Ω Ω Ω
(spark plug cap – spark plug cap)
