USING CHECKSPARK
1.
IMPORTANT
- For correct CheckSpark operation, always set
engine-type slide switch to the proper engine type being tested
Vehicles
Small gas engines
2. Connect CHECKSPARK to plug wire of a non-running engine (see Fig. 1)
3. Push gripper lever forward to open plug wire hook
4. Place open gripper hook on plug wire and release gripper lever
5. Red LED will stay lit indicating unit is ready for test
6. Disconnecting CHECKSPARK from plug wire will reset the internal circuit
7. CHECKSPARK may also be reset (if a second test is desired) by
momentarily pressing the reset button without the need to remove the
tester from the plug wire (see Fig. 2)
Fig. 1
PULL START ENGINES
1. Insure engine is ready for starting (see owners manual if necessary)
2. Firmly pull the recoil starter one time, if engine starts turn off engine
3. Observe LED status on the CHECKSPARK tester (see Fig. 2)
ELECTRONIC IGNITION ENGINES
1. Insure engine is ready for starting (see owners manual if necessary)
2. Energize electric start only long enough to turn engine over several times, if
engine starts turn off engine
3. Observe LED status on the CHECKSPARK tester (see Fig. 2)
CHANGING THE BATTERY
1. Remove battery cover by pushing in
on rear tab of battery cover and pulling
up at same time (see Fig. 3)
2. Observe polarity when installing
battery, + terminal is toward the rear of
the unit (see Fig. 4)
3. Reinstall battery cover
4. Battery check: Push gripper
lever forward, red LED will light
indicating battery is good and unit is
operational

CheckSpark Operation
Read these instructions completely before use
AFTER ATTEMPTING TO START ENGINE
LED on CHECKSPARK tester will now show condition of the spark (see Fig. 2)
OK – GREEN (flashing)
Proper voltage, ignition is OK
Too HIGH – YELLOW (flashing) High voltage (see chart for possible causes)
Too LOW – RED (not flashing) No voltage (see chart for possible causes)
Too LOW – RED (flashing)
Low voltage (see chart for possible causes)
DIAGNOSTIC CHART
LED STATUS LIGHTS
Flashing GREEN (OK)
Solid RED (Too LOW)
• Spark voltage is OK
• Compression is good
Flashing RED (Too LOW)
• No start problem could be:
Flashing YELLOW (Too HIGH)

choke setting, defective
carburetor or fuel injector
Solid RED (Too LOW)
Flashing RED (Too LOW)
Flashing YELLOW (Too HIGH)
• Spark voltage is too high
• Broken spark plug
