What causes no power to the ignition coil?

You may have a bad ignition module. You can check it by removing the affected ignition coil, also remove the fuel injector fuse. Connect a test lamp across the two terminals on the ignition module. Take a look at the test light while you crank the engine over.

Where does the ignition module receive its power?

The electronic ignition control module is a solid state “On/Off” switch for the ignition system. The module receives a signal from a sensor inside the distributor. The signal is then used to fire the ignition coil creating the energy for the spark plugs.

What does the ignition coil connected to?

The ignition coil connects to the rotor, and the rotor spins around inside the cap. The coil passes a high-voltage pulse through the rotor each time it passes a contact in the cylinder, transferring its power to the engine.

What gives the coil power?

The electrical system in your vehicle works on 12 volts, so every component must be based on 12 volts, as well. There is a wire connected to the ignition coil (known as a “hot wire”) that carries the 12 volts into the coil itself. The power is initially created in the battery and alternator setup.

What gives power to the coil?

Two positions of the ignition switch provide power to the positive primary post of the ignition coil. In the “start” position, the switch energizes the starter motor, and full battery voltage is directed to the coil while the engine cranks. Once the engine starts, the switch is released to the “run” position.

How do I know if my distributor has power?

Check the Arc Place the metal screwdriver near the electrode of the distributor. It should not touch the electrode. Step away from the hood and have someone watch the arc while the ignition is turned on. If there is an arc, it is firing.

Where do the coil wires go?

Connect the positive (+) coil lead wire to the positive (+) terminal of the coil using a small combination wrench. Connect the negative coil lead wire to the negative (-) terminal of the coil. Insert the high tension lead wire into the center post of the coil making sure it fully seats.

How do I get power to my distributor?

The plug which is pointing right at you provides power for the electronics inside the distributor (green box). This is low voltage power. To power the spark plugs, the distributor is powered from a coil through the cap. The connection for that is on the right hand side (red arrow).

How do I know if my ignition coil has power?

Locate the positive or power wire attached to the engine coil. Check for power using a test light. If this wire has no power, then your ignition coil is not receiving current. You should check the wiring from your ignition switch to the coil for breaks in the wire and repair them.

Where does the ignition coil output voltage come from?

The ignition coil is the heart of the ignition system. As current flows through the coil a strong magnetic field is built up. When the current is shut off, the collapse of this magnetic field to the secondary windings induces a high voltage which is released through the large center terminal.
