Car Engine Points

Overview

Car engine points are a critical part of the ignition system. They are responsible for delivering the spark that ignites the air-fuel mixture in the cylinders. Without properly functioning points, the engine will not be able to run.

Points are typically made of a contact breaker and a condenser. The contact breaker is a switch that opens and closes to allow current to flow to the coil. The condenser stores energy and releases it when the contact breaker opens, which creates a spark at the spark plug.

Types of Points

There are two main types of points: mechanical and electronic.

Mechanical points are the most common type of points. They are relatively simple and inexpensive to replace.
Electronic points are more precise than mechanical points. They use a transistor to control the flow of current to the coil, which results in a more consistent spark.

Symptoms of Bad Points

There are a number of symptoms that can indicate that your car’s points are bad. These symptoms include:

Engine misfiring
Hard starting
Reduced engine power
Increased fuel consumption
Backfiring

Replacing Points

Replacing points is a relatively simple task that can be completed in about an hour. However, it is important to follow the manufacturer’s instructions carefully to avoid damaging the points or other components of the ignition system.

To replace the points, you will need the following tools:

Socket wrench
Feeler gauge
Screwdriver
New points

Once you have the necessary tools, follow these steps to replace the points:

Disconnect the negative battery terminal.
Locate the points. They are typically located on the side of the distributor.
Use a socket wrench to loosen the bolts that hold the points in place.
Carefully lift the points out of the distributor.
Install the new points in the distributor.
Tighten the bolts that hold the points in place.
Use a feeler gauge to set the point gap. The point gap should be specified in the manufacturer’s instructions.
Reconnect the negative battery terminal.
Start the engine and check for proper operation.

Conclusion

If you suspect that your car’s points are bad, it is important to have them replaced as soon as possible. Replacing points is a relatively simple task that can be completed in about an hour. However, it is important to follow the manufacturer’s instructions carefully to avoid damaging the points or other components of the ignition system.
