What's an ignition coil? The ignition coil is an integral part of the ignition system in internal combustion engines. Its primary function is to transform the low-voltage electrical power from the car battery into the high-voltage electricity needed to create sparks in the spark plugs. ...
Spark plugs should normally be replaced once the engine is cool, and parts may need to be temporarily removed to access the plugs. How often should you replace spark plugs? An effective spark plug might work for many years and many thousands of miles. As always, it’s best to check your...
The car ignition coil is a transformer capable of providing high-voltage pulses. The purpose of these pulses is to create a spark (arc) between the electrodes of the spark plug of an internal combustion engine, of sufficient strength and duration to properly initiate the internal combustion of ...
If the ignition coil is properly connected, use a CDI tester to test the CDI box. Intermittent or weak spark: If you’re getting an intermittent or weak spark, check the spark plugs to make sure they’re clean and in good condition. If the spark plugs are in good condition, use a ...
An OBD/OBD2 scanner will read the codes, which can then point you towards which sensors or parts need replacing. However, it is important to keep in mind, that just because a part is reading bad on the computer, it doesn’t necessarily mean that part is bad. A broken or damaged wire...
Bad Ignition Switch When you turn the key to start the car, the ignition switch, which is installed behind the ignition lock, gets turned. Inside the ignition switch are many tiny metal plates that can build up rust over time. When this happens, one of these plates may lose connection, ...
First things first,what exactly is a spark ignition fuel? Well, the term spark ignition refers to a system in which the air-fuel mixture inside the combustion chamber of an engine is ignited by a spark. The system uses an electrical field made inside a magnet or coil, which builds thousan...
like a large jolt or bang; this is when unburnt fuel is ignited when it wasn’t supposed to be. This incorrect fuel ignition not only puts a lot of strain on the engine, but also potentially damages the car’s catalytic converter, which is an expensive emissions-related component to ...
1. Bad Ignition Coil The most common cause of an engine misfire is a bad or failing ignition coil. Some vehicles have a separate ignition coil on every spark plug, while some cars have one coil pack with an ignition wire to each spark plug. Older cars use a distributor to distribute the...
If pressures at both gauges drop when the PTO is engaged, then there is likely a failed O-Ring inside the PTO, and the PTO will need to be disassembled and repaired The solenoid coil has failed Check the coil for continuity An open circuit means the coil has burned ...
