Coil on plug wiring diagram – I’m sure you’ve seen those old car engines with the spark plug wires coming off of the distributor cap and running to each spark plug. This is called a “coil on plug” (COP) ignition system, and it’s much more efficient than the old style. In fact, COP systems are now used on almost all modern engines.
But how do they work?
If you’re looking for a coil on plug wiring diagram, you’ve come to the right place. Here at BlueDriver, we have all the information you need to get your car up and running in no time.
A coil on plug (COP) ignition system is a type of ignition system that uses individual coils for each spark plug.
This system is used on many modern vehicles and offers several advantages over traditional ignition systems.
One advantage of COP systems is that they eliminate the need for spark plug wires. This means there are fewer potential failure points in the ignition system and less chance for misfires.
COP systems also tend to produce more powerful sparks, which can improve engine performance.
If you’re converting your vehicle to a COP ignition system or just need a replacement wiring diagram, we’ve got you covered. Our comprehensive database has everything you need to know about coil on plug wiring diagrams.

What Wires Go to the Ignition Coil?
The ignition coil is one of the most important parts of your car’s engine. It’s responsible for providing the spark that ignites the air/fuel mixture in the cylinders, and it can be a real pain if it goes bad. But what exactly does an ignition coil do, and how do you know if yours is going bad?
In order to understand what an ignition coil does, it’s important to first understand how a car’s engine works. The engine contains a series of cylinders, each of which contains a piston that moves up and down. When the piston moves up, it draws in a mixture of air and fuel; when it moves down, this mixture is compressed.
At the top of the compression stroke, the spark plug fires, igniting the air/fuel mixture and causing the piston to push down on the crankshaft, which turns the wheels. The whole process then repeats itself over and over again hundreds or even thousands of times per minute.
So where does the ignition coil come into play?
Well, every time the spark plug fires, it needs a burst of electricity to create the spark. This electricity comes from the battery, but it has to be boosted up to a high enough voltage before it can jump across the gap in the spark plug (which is why they’re called “spark” plugs). That’s where the ignition coil comes in.
The ignition coil consists of two coils of wire wrapped around an iron core.
How Do You Test a 3 Wire Ignition Coil?
An ignition coil is a type of transformer that steps up the low voltage from the battery to the high voltage needed by the spark plugs. A 3 wire ignition coil is typically used in an internal combustion engine. The first wire goes from the positive terminal on the battery to one side of the primary winding on the ignition coil.
The second wire goes from the other side of the primary winding to ground. The third wire goes from the negative terminal on the battery to one side of the secondary winding on the ignition coil. The other side of this winding is connected to either a spark plug or a distributor, depending on whether your engine uses a distributorless ignition system or not.
To test a 3 wire ignition coil, you will need a multimeter that can measure AC voltage. First, disconnect all three wires from the coil. Then, set your multimeter to measure AC voltage and touch one probe to each ofthe two terminals onthe primary winding (the ones that were connectedto teh battery).
You should see somewhere between 0.5 and 2 volts AC when doing this test – if you don’t, then there is something wrong with either your multimeter or your ignition coil and it needs to be replaced.
Next, connect your multimeter probes to each ofthe two terminals onthe secondary winding (the ones that go tot he spark plug or distributor). This time you should see somewhere between 10 and 20 volts AC – if not, then again eitheryour multimeteror yourignitioncoilneedsreplacing.
If both tests show proper readings, then congratulations – your 3 wire ignition coil is working fine!
Where Does the Wire on the Positive Side of the Coil Go?
The wire on the positive side of the coil goes to the distributor. The distributor is responsible for distributing the spark to each cylinder in the correct order. The coil itself contains two sets of windings: a primary winding and a secondary winding.
The voltage from the battery is applied to the primary winding, which then produces a magnetic field. This magnetic field induces a current in the secondary winding, which is then sent to the spark plugs.
How Do You Test a 4 Wire Ignition Coil?
A four wire ignition coil is typically used in older model cars. The four wires are the primary winding, the secondary winding, the ground, and the trigger or spark input. To test a four wire ignition coil, you will need to check for continuity between each of the four wires.
The first step is to disconnect all four wires from the coil. Using a multimeter set to ohms, touch one lead of the multimeter to each terminal on the coil and check for continuity. There should be continuity between each of the terminals and their corresponding wire.
If there is no continuity, then that means there is an open circuit and the coil needs to be replaced.
Once you have verified that there is continuity between all of the terminals and their corresponding wires, it’s time to test for resistance. Again using your multimeter set to ohms, touch one lead of the multimeter to each terminal on the coil and check for resistance.
The resistance values can vary depending on the type of coil being tested, but as a general rule of thumb you should see a reading of around 5-6 ohms on the primary winding and around 20-30 ohms on secondary winding. If your readings are outside of this range then it’s possible that there is an issue with your ignition coil and it will need to be replaced.
