When do you remove the ground wire from the ignition coil?
When do you remove the ground wire from the ignition coil?
1. Remove the ground wire from the coil. 2. Start the engine ( turn the key ) 3. See how well the engine runs. Does it cut out? I guess what I don’t understand is the little wire ( ground wire ) is what tells the engine to quit when you turn the key off?
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.
What to do if your ignition coil is not working?
Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor. The ignition module uses the information to time spark generation. Test these components if the energized coil fails to function.
What causes an open circuit in an ignition coil?
Any break in a conductive material, like a wire, creates an open circuit. An open circuit behaves as though it were switched off. The windings in an ignition coil are no more than thin wires, and open circuits can occur inside the coil. You can test the continuity of coil windings by measuring the resistance with an ohmmeter.

Why does my car run after turning off the ignition?
This is the tendancy for this year car to stay running for several seconds after turning the key off. This is not the classic “Dieseling” that is caused by hot spots con- tinuing to burn fuel after shutting off the ignition, rather it is the engine just run- ning normally for a short time after turning the key off, then eventually shutting off.
What can cause an ignition switch to fail?
(These generalizations, depend significantly on year, make, and model.) Worn ignition switch contacts, temperature problems, or broken springs can all cause the ignition switch to fail, preventing you from starting your car. On the road, poor ignition switch contacts could shut the engine off while driving, which could be dangerous.
What to do if your ignition cylinder is worn out?
How To Fix It: Fortunately, this is an easy fix. Just turn the wheel back and forth until the ignition cylinder is freed. It’s a fact of life that mechanical things tend to wear out, and the same goes for mechanical keys and key cylinders used in your car’s ignition system.
Why does my ignition coil keep going out?
Here is why! The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding.
How can I disable a distributor ignition system?
Below is a simple schematic of a distributor ignition system. The best way to disable any ignition system is to unhook the primary circuit. This may be a simple as removing a fuse, or you can find the primary wires to the coil or coils and unplug them. All ignition coils have a primary and secondary circuit.
What to do if your ignition coil is on fire?
Replace the coil with a good quality new one, make sure you attach and tighten the leads correctly, plug in the top cable that goes to the distributor, turn the key and you should be good to go!
What happens if the ignition coil does not work?
If your ignition coil does not transmit enough energy to the spark plugs in your car, your vehicle will have to burn and use extra fuel. This is the only way that the vehicle can keep running – by burning the extra and residual fuel.
When is the distributor replaced by the coil pack?
When the energy reaches the spark plugs, it starts the combustion process. In more modern cars today, the distributor is replaced by the coil pack. This is typically because the coil pack is more reliable and consistent than the distributor.
How is the ignition coil connected to the distributor?
Connect the positive terminal of the ignition coil to the “On” terminal of the ignition switch. Connect the negative terminal of the ignition coil to the coil terminal of the distributor.
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.
