1. IMPORTANT-For correct CheckSpark operation, always set engine-type slide switch to the proper engine type being tested

swith

2. Connect CheckSpark to plug wire hook
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 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 nFlg.2)

ELECTRONIC IGNITION ENGINEScar

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 status on the CheckSpark tester (see Fig.2)

PULL START ENGINESmower

1. Insure engine is ready for starting (see owners manual if necessary)
2. Frimly pull the recoil starter one time, if engine starts turn off engine
3. Observe LED status on the CheckSpark tester(see Fig.2)

AFTER ATTEMPTING TO START ENGINE
LED on CHECKSPARK tester will now show condition of the spark (see Fig.2)
OK - GREEN (flashing) Proper voltage, ingnition is OK
HIGH - YELLOW (flashing) High voltage (see chart for possible causes)
LOW - RED (not flashing) No voltage (see chart for possible causes)
LOW - Red (flashing) Low voltage (see chart for possible causes)
DIACNOSTIC CHART
LED STATUS LIGHTS

greenFlashing GREEN (OK)

  • Spark voltage is OK
  • Compression is good
  • No start problem could be
  • Lack of fuel, bad fuel, improper choke setting, defective carburetor or fuel injector

yellowFlashing YELLOW (HIGH)

  • Spark voltage is too high
  • Broken spark plug
  • Plug wire not properly connected/seated on spark plug
  • Plug wire resistance too high (resistor type plug wire)
  • Broken or open plug wire
  • Improper spark plug gap
  • Check slide switch setting-CheckSpark may flash yellow if slide switch not on correct engine type setting

red1Solid RED (LOW)

  • No spark detected
  • Engline kill switch not in run position
  • Defective trigger swith (electronic ignition)

  • No primary voltage at coil (electronic start engines)
  • Open plug wire at coil output

redFlashing RED (LOW)

  • Spark voltage too low
  • Flooded engine
