Dizzy cap

Post by cavdan »

Hi all!
Just thought I'd say hello and introduce myself to the group.
Also, try and put a 100% answer to my question. Is this dizzy cap kaput? Some people telling me it's fine and some people telling me it's no good.
Any help appreciated.

Hi Dan,

Welcome to the forum,

I cannot see any images / pictures, so I cannot offer a 100% accurate opinion.

If there is any dirt or moisture, then give the cap a good clean.

If the internal contacts are crusty or deeply burnt, then I would replace it with a new one.

It might be worth looking at the condition of the rotor arm too.

If all they need is a very light clean with some wire wool or fine emery cloth, then they could probably be refitted.

-------------------------------------

What ignition / engine set-up do you have.?

The usual weak spot is the H T leads, rather than the distributor or rotor.

--------------------------------------

As a separate comment.

Take a look inside the exterior terminals of the distributor cap.

There are two main types of connector.

Some are just a socket,
And some have a socket with a brass stud / screw thread inside.

Which ever you have,
you need to ensure that any parts you replace,
will match any parts that you don't.
(Dizzy cap, H T leads etc)
