*Note
• When there is no spark in the spark plug, it is
necessary to check whether the parts of wiring are
loosened or in poor contact;
• There are many brands of multimeter, the internal
impedances are different and the tested values are
different.
●Check the primary coil
●Measure the impedance among the terminals of
primary coil.
Standard value: (4±10%)Ω
（

★
The impedance value is good in the standard value.
★
If the impedance value is “∞”, it indicates that the
wire in the coil is disconnected and the ignition coil
needs to be replaced.
