This test can be made without removing parts.
1. Measure ignition coil resistance. Replace if other than
specified value.
Ignition Coil Resistance :
Primary Side :
Secondary Side : Between c and b 6.8 - 10.2 kΩ
4) Inspection of Exciter Coil
• Measurement of resistance
1. Disconnect all connectors from coil plate ass'y, and
measure resistance between terminals.
Replace exciter coil if the resistance is out of specified
range.
Exciter Coil Resistance :
Red (R) – Blue (L): 210 Ω
• Measurement of peak volts
1. Connect Peak Voltage adapter to exciter coil connectors.
2. Measure peak volts at shown below.
Replace exciter coil or check connection of wire harness if
the peak volts out of specified range.
Exciter Coil Peak Volts: (Reference)
Red (R) – Blue (L)
Between a and b 0.4 - 0.6 Ω
(without plug cap)
260 V at cranking (500 r/min)
280 V at idling (1000 r/min)
220 V at 1500 r/min
150 V at 3000 r/min
