Can bad points cause no spark?
If no spark, remove the wire from the points and manually “spark” it to ground. 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 do I know if my points are bad?
Here are some common symptoms that hint towards having failing points and condenser:
- Vehicle not starting. If your vehicle will not start, it is possible there is a problem somewhere within the points and condenser.
- Engine will not fire.
- Engine runs rough.
Why do ignition points fail?
As they close, current from the ignition switch flows through the contacts into the coil’s primary windings and then off to ground. When the points open a few degrees of crankshaft rotation later, the current is interrupted, causing the magnetic field to collapse.
What to do if your points have no spark?
If no spark, remove the wire from the points and manually “spark” it to ground. If spark, then problem is bad points or condensor. If no spark, then the problem is coil or the wire to the points.
What should I do if my points are not working?
First check for power to the coil. If you have 12v there, then manually open the points and check for spark from the coil. If no spark, remove the wire from the points and manually “spark” it to ground. If spark, then problem is bad points or condensor.
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.
How can I tell if my coil has no spark?
If you have 12v there, then manually open the points and check for spark from the coil. If no spark, remove the wire from the points and manually “spark” it to ground. If spark, then problem is bad points or condensor. If no spark, then the problem is coil or the wire to the points.
