CRANKING OUTPUT TEST WITH PEAK READING VOLTMETER
The following peak voltage tests will measure the amount of output directly from each component. A peak reading
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
compare to the chart. The following measurements are obtained when cranking the engine with the electric start-
er, spark plug installed. The starter system must be in good condition and the battery fully charged.

CDI OUTPUT TEST USING PEAK READING ADAPTOR
Re-connect all CDI wires to stator wires. Disconnect CDI module wire from ignition coil primary terminal. Connect
one meter lead to engine ground and the other to the ignition coil primary wire leading from the CDI module. Crank
engine and check output of CDI wire to coil (130 DCV). Reconnect coil wire to CDI.
Output w/ Peak output tester
130 DCV
Average Output w/ Digital Voltmeter
20 DCV
