IGNITION
90-857046R1 NOVEMBER 2001 Page 2A-13
CAUTION
To protect against meter and/or component damage, observe the following precautions:
• 400 VDC* test position (or higher) MUST BE used for all tests.
• INSURE the Positive (+) lead/terminal of DVA is connected to the Positive (+) recep-
tacle of meter
• DO NOT CHANGE meter selector switch position while engine is running and/or be-
ing “cranked”.
• ALL COMPONENTS MUST BE GROUNDED during tests. Running or “cranking” en-
gine with CDI or Ignition Coils ungrounded may damage components.
* If using a meter with a built-in DVA, the DVA/400 or DVA/500 VDC test position should be used.
NOTE: Test leads are not supplied with the Direct Voltage Adapter (p/n 91-89045). Use test
leads supplied with multi meter.
Test procedures and specifications are provided for checking primary ignition voltage
while the engine is running and/or being “cranked” with all harnesses connected.
Ignition Troubleshooting
WARNING
DANGER - HIGH VOLTAGE/SHOCK HAZARD! Do not touch ignition components
and/or metal test probes while engine is running and/or being “cranked”. STAY
CLEAR OF SPARK PLUG LEADS. To assure personal safety, each individual spark
plug lead should be grounded to engine.
WARNING
When testing or servicing the ignition system, high voltage is present. DO NOT
TOUCH OR DISCONNECT any ignition parts while engine is running.
Tool: Multimeter/DVA Tester 91-99750A1 or DMT 2000 Multi-Meter with Direct
Voltage Adaptor (p/n 91-89045).

NOTE: If using DMT 2000 turn the selector switch to DC volts. Allow the meter to auto-range.
(1) Readings may vary at cranking speed or at idle speed.
(2) Back probe the electrical lead bullet connector in order to make connection.
