How does a dual point ignition work?

How does a dual point ignition work?

With the dual points distributor, the first points set to close “makes” the circuit and will incur any ravages caused by a small amount of arcing when closing. The last points set to open “breaks” the circuit and will incur any ravages caused by a small amount of arcing when opening.

Do you need to reset spark timing with dual points?

Then you may need to go back and check/reset the timing again, as the dwell adjustment could have changed the spark timing. With dual points you set the gap on both sets of points, then set the timing, which is controlled solely by the secondary points (which open last).

How to troubleshoot a points ignition system page?

– Check for continuity between the ignition switch purple lead and the boat side female harness connection. If there is no continuity, you may need to run a new 12 volt (+) wire from the key switch to the boat/engine harness. – Remove the distibutor cap and inspect.

Why do you need a dual point distributor?

In the interest of maintaining accurate spark timing, there is a vested interest to minimize changes of dwell, which leads to an interest in decreasing wear on the contact points. With the dual points distributor, the first points set to close “makes” the circuit and will incur any ravages caused by a small amount of arcing when closing.

What to do if your ignition system is failing?

The ignition system can be a complicated system, especially to someone who has never worked with them before, so it is best to contact professional mechanic to diagnose and repair the problem. From there, the mechanics can replace the points and condenser system if needed, so you can have your vehicle up and running in no time.

Why is my ignition system not working properly?

Breaker point systems: used on engines made before 1980, these systems use a mechanical switch instead of a transistor to close the electrical circuit used to produce a spark. If you are experiencing ignition timing issues, this is most often due to a sheared flywheel key.

Then you may need to go back and check/reset the timing again, as the dwell adjustment could have changed the spark timing. With dual points you set the gap on both sets of points, then set the timing, which is controlled solely by the secondary points (which open last).
