Where are the plugs and coils on a cop ignition system?

COP ignition systems are used on many late model engines. On most applications, the plugs and coils are located on top of the cylinder head for easy mounting of the coils. A topside location is best because it keeps the coils away from the heat of the exhaust.

Is it possible to replace a coil and spark plugs?

Yes. If that is the case then try switch the boots (i take it they are not apart of the coil pack) and see if it happens then. Basically try to track down what part it is by switching stuff around.

How are the windings of a ignition coil insulated?

The primary winding has relatively few turns of heavy wire. The secondary winding consists of thousands of turns of smaller wire, insulated from the high voltage by enamel on the wires and layers of oiled paper insulation.

How are the contacts on an ignition coil driven?

The contacts are driven off a shaft that is driven by the engine camshaft, or, if electronic ignition is used, a sensor on the engine shaft controls the timing of the pulses. The amount of energy in the spark required to ignite the air-fuel mixture varies depending on the pressure and composition of the mixture, and on the speed of the engine.

What can cause an arc through the plug wires and the coil?

Look for a carbon-impregnated string in the spark plug burned away from the terminal. That is the single biggest reason for a misfire, and new wires will take care of that. That makes it hard for the spark to get to the plug so it looks for an easier way to get back to ground. helpful? Thank you for your help, I found the problem.

How do you find an arcing ignition coil?

Push the wire pin connector back into its socket. Connect the negative battery cable with a socket. Start the engine. With the engine running in a darkened garage, you can find an arcing coil by seeing a stray voltage arc, which looks like a small bolt of electricity, accompanied by an electrical “snapping” sound.

Where is the coil pack on a car?

Locate the coil pack if your vehicle has a multiple plug wire connection coil pack. Pull the coil pack wire out of its pin connector by depressing the tabs and lifting up. Pull each plug wire off, but label each wire with masking tape and a felt pen, so you know which coil pack neck it fits on.

How long does it take for a spark plug wire to arc?

A connection is made to apply 12vdc to a coil. Current starts to flow but it is opposed by the induction of the coil. The voltage slowly overcomes the induction and more current flows. Current flow increases with time. At higher RPMs, it may only have 1/5000th of a second (200 microseconds) to build up, but in electrical time, thats a lot.
