Ignition Test Procedures
Direct Voltage Adapter (DVA)
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, while key
switch is on or while battery cables are connected.
CAUTION
Failure to comply with the following items may result in damage to the ignition sys-
tem.
1. DO NOT reverse battery cable connections. The battery negative cable is (–) ground.
2. DO NOT “spark” battery terminals with battery cable connections to check polarity.
3. DO NOT disconnect battery cables while engine is running.
4. DO NOT crank engine with CDI or Ignition Coils not grounded.
CAUTION
To protect against meter and/or component damage, observe the following precau-
tions:
• 400 VDC* test position (or higher) MUST BE used for all tests.
• INSURE the Positive (+) lead/terminal of DVA is connected to the Positive (+) receptacle
of meter.
• DO NOT CHANGE meter selector switch position while engine is running and/or being
“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. 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.
