CRANKING OUTPUT TEST WITH PEAK READING VOLTMETER
Thefollowingpeakvoltagetestswillmeasuretheamountofoutput directlyfrom eachcomponent. Apeakreading
voltmeter must be used to perform the tests
. A variety of peak reading adaptors are commercially available for
use with the Fluke ™ 73 Digital Multitester, Tektronix DMM155, and other digital VOMs which will allow peak volt-
age tests to be performed accurately. Follow the directions provided with the adaptor . All measurements are
indicated in DC Volts. Readings obtained without a peak reading adaptor will be significantly different.
Disconnect the stator connectors from the CDI module. Test output from exciter coil, pulse (trigger) coil, and
comparetothechart. Thefollowingmeasurements areobtainedwhencranking theenginewiththe electricstart-
er, spark plug installed. The starter system must be in good condition and the battery fully charged.
