How can you tell if a coil wire is bad?

How can you tell if a coil wire is bad?

Symptom 1. If the engine stops and starts erratically while driving, or if it cuts out altogether and refuses to restart, you may have a bad wire between the coil and the distributor. Constant movement, caused by engines vibration and the wire’s tendency to flex slightly, fatigues the wire’s central core.

Where is the coil wire?

The ignition coil wire sits in the ignition distributor of your car and transforms the battery’s voltage to the voltage needed to stimulate your spark plugs. The voltage from a battery is only 12 volts. A spark plug needs thousands of volts to have enough energy to turn your engine over.

Where does the negative side of the coil go to?

When you hold the coil so the plug wires are to the left (like standard shovel or evo mounting, mounting holes at the rear), the negative side is on the top and the positive is on the bottom.

Does negative side of coil go to ground?

One end of the secondary is grounded (the ‘negative’ terminal), the coil produces the voltage (the ‘battery’) and the output goes out the ‘positive’ terminal to the spark plug, where it jumps the spark gap and returns to ground, completing the circuit.

Where does the coil wire go on a car?

Connect the positive coil wire to the positive terminal of the ignition coil. Locate the negative coil wire. On most cars made before 1980, this wire connects to the points switch, which is located on the distributor.

Where is the positive coil on an engine?

The two primary terminals are usually labeled positive and negative. Check the engine repair manual for your make and model car before beginning work. Locate the positive coil wire, which runs from the ignition switch to the positive terminal of the ignition coil.
