The Coil On Plug (COP) Quick Ignition tester is a battery-operated, hand-held quick tester designed to easily and quickly determine if a COP is producing a proper spark for the plug.

The quick tester works by receiving a signal from the secondary ignition coil. Once the signal is received, the tester determines if the COP is producing the correct amount of voltage and the duration of the arc. If the voltage is correct, the tester beeps and the red LED light flashes; and if the duration of the arc is correct, the green LED will also flash
Test Results

Red LED Light
Consistent, steady flashing and beeping indicates the COP is producing the correct amount of voltage.

No response or an inconsistent response indicates the COP is NOT producing the correct amount of voltage. This may be caused by one of the following:

  1. Fouled spark plug, or incorrect gap
  2. Damaged/corroded wires or connectors
  3. Faulty coil or PCM

Green LED light
Consistent and steady flashing indicates the duration of the arc is correct.

No response or an inconsistent response indicates the duration of the arc is NOT correct. This may be caused by one of the following:

1.Shorted windings inside the coil
2. Resistance or bad connections in the
3. primary / secondary connections
4. Faulty coil

The kV/Arc Quick Tester is a battery-operated, hand-held tester designed to easily and quickly check the presence of a spark in the vehicle's cylinders, determine the polarity (+/-), and measure the peak voltage as the spark plug is firing on Distributor and Oistributodess ignition Systems.

The tester works by receiving a signal transmitted from the spark plug's wire. In the Quick Check Mode, the red LED light flashes when a spark is detected, If the polarity is negative (-), the green LED lights; and if positive (+),the red LED lights. In the Measurement Mode, the tester  measures and displays the peak spark voltage for approximately 15 seconds.
Test Results

Quick Check Mode
To enter the Quick Check Mode, simply turn the tester on. The tester automatically enters this mode when it is powered on.
During this mode, the red and green LEDs alternately flash once every second until a spark is detected.
Once a spark is detected, the Red LED light flashes and the red or the green LED lights to show the polarity.

Notes:
If the tester does not detect a spark after 30 seconds, it automatically turns off.
， The Quick Check Mode may not detect spark voltage less than 5 kV. Use the Measurement Mode to verify.

Measurement Mode
During this mode, the red and green LEDs stay lit while the tester measures the peak spark voltage (for approximately 10 to 15 seconds).
When the tester finishes a measurement, it will do all of the following:
，The tester emits a beeping sound
，The headlight flashes 3 times
，The corresponding polarity LED lights
，LCD displays the current KV reading for 15 seconds
