*What's Peak Voltage
It is the method peak voltage measurement, at one of decision method of ignition system and charge system, of turning
the flywheel and peak voltage (instantaneous maximum voltage) measuring dynamically.
Merit of adoption of peak voltage measurement
1.At the precision which is higher than past of decision and defective place or parts can be executed much faster.
2. Good or faulty condition can be checking without removing the parts.
Recommended tester
Notes:
1 Use HIOKI HiTESTER MODEL 3030 or equivalent tester for this measurement, and do not use megger or
other instrument.
2 Disconnect all connections, and measure as an independent unit.
3 When the tester's pointer moves, the result is "ON", or "OFF" when not.
4 The value enclosed by ( ) is approximately value measured using 1kΩ range of the tester. Note that the value
varies among conditions of the tester (internal power supply), measurement ranges and models.
5 Perform this inspection only as a guide.
