Should ignition points spark?
Points shouldn’t spark when the engine is running but they might while you’re working on it. The points are the grounding circuit for the primary side of the ignition coil. If the secondary side is not completed – spark plugs in and hooked up, (make sure the plug leads are good) you can get a spark across the points.
What does the condenser do in points ignition?
The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field.
Will points spark if coil is bad?
If spark, then problem is bad points or condensor. If no spark, then the problem is coil or the wire to the points. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
How is a condenser connected to a spark plug?
The condenser is attached to the system by breaker points. The condenser and distributor rotate so that the points open and close continuously. The current from the ignition flows through the contacts and sends the voltage to the spark plugs, which ignite the fuel.
How to troubleshoot a no spark car engine?
I am grateful for the help. First, check for 6 volts between the negative terminal of the coil and ground while the engine is cranking. If you get 12 volts, the points are not conducting when closed, if you get 0 volts, you are not getting any voltage to the coil or the points are not opening.
Why is there no spark at the contact points?
I appreciate it. A spark at the contact points might possibly be seen but not seeing a spark does not indicate a lack of current. The voltage at the points is minimal compared to the coil output. Another possibility is corrosion on the rotor, or the contacts in the distributor cap. Yup.
How does a condenser and distributor work in a car?
The condenser and distributor rotate so that the points open and close continuously. The current from the ignition flows through the contacts and sends the voltage to the spark plugs, which ignite the fuel.
