Trigger - Generic TR 125 Service Manual

6.5.2 Primary coil inspection
Measure the impedance between terminals of primary coil.
Standard value: 0.4Ω±10% (20 )
Impedance value within the range is good.
Impedance value "∞" indicates broken wire inside the coil. The coil shall be replaced.
6.5.3 Secondary coil
Attached with the spark plug, and measure the impedance
between lead-wire side of spark plug cap and terminal.
Standard value: 8-11KΩ (20 )
Impedance value within the range is good.
Impedance value "∞" indicates broken wire inside the coil.
Blue/ White
Remove the spark plug cap and measure impedance value
between primary side lead-wire of ignition coil cap and
negative terminal.
Standard value: 4.5-5.5KΩ±10% (20 )

6.6 Trigger

* Attention
Trigger inspection can be performed on the
engine.
Inspection
Remove protecting plate of vehicle block.
Remove lead-wire connector of trigger.
Measure the impedance between blue/white terminal of
lead wire at engine side and grounding vehicle block.
Standard value: 100-200Ω (20 )
If measured impedance value is beyond the range, please
replace the alternator.
