Where does the wire run on an ignition coil?
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. On later model cars, this wire may run back to the car’s computer or the ignition control module.
What does it mean when your ignition coil is orange?
If the spark is orange or some similar color. Either the coil is weak and is going bad or you do not have proper voltage going into the coil. If you have a weak spark coming from the spark plug, lets check the ignition input voltage first. On the plug there is a green and a white wire.

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.
How are the coils on a car controlled?
Coils on older model cars — or those made before 1980 — were controlled by a mechanical switch commonly called points. Later model cars have the coil controlled by engine electronics. Most coils have three or four terminals.
How many terminals does an engine coil have?
Most coils have three or four terminals. Two terminals power the primary coil and the other terminal or terminals provide the high voltage from the secondary coil. The two primary terminals are usually labeled positive and negative. Check the engine repair manual for your make and model car before beginning work.
What happens when you replace the coil wire on an engine?
You can replace the secondary coil wire on an engine that uses one with an equal length of vacuum hose and the engine will start and run. The powerful spark will travel down the hollow hose to the distributor cap, but the engine will stall under any load because of the weakened spark.
Where is the positive coil wire on a car?
Locate the positive coil wire, which runs from the ignition switch to the positive terminal of the ignition coil. On later model cars, this wire may run back to the car’s computer or the ignition control module. Connect the positive coil wire to the positive terminal of the ignition coil. Locate the negative coil wire.
What happens if there is no spark in the ignition coil?
Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Simply put, the bottom line is without spark the engine doesn’t run.
