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 spark plug.
It works by receiving a signal from the secondary ignition coil and determines if the COP is producing the correct amount of voltage and arc duration. If the voltage is correct, the tester beeps and the red LED light flashes; if the arc duration is correct the green LED will also flash.
Quickly diagnoses faulty ignition coils
Auto power off
Probe length including end sensor 200mm
Powered by CR2032 battery supplied
Handset 130L x 55H x 22W mm
RED LIGHT - Spark
Consistent, steady flashing and beeping indicates the COP is producing the correct voltage.
GREEN LIGHT - Arc
Consistent and steady flashing indicates the arc duration is correct.
NO LIGHT OR INCONSISTENT RESPONSE
Indicates the COP is NOT producing the correct voltage. This may be caused by the following:
1. Fouled spark plug, or incorrect gap
2. Damaged or corroded wires or connectors
3. Faulty coil or PCM
