My A has run poorly at times lately, sputtering, cutting out and bucking as though at times its not getting enough spark. Some times it ran fine, especially when started, but quickly had the issue again.

Anyway, replaced the coil, and no luck. Tried to replace the condenser, and now it wont start. And seems to be getting no spark (pulled a plug and held it against the motor, and nothing).

Can someone tell me how the condenser gets wired? Does the wire from it go on top of the plastic washer (with the nut then on top of it), and the other wire attached to the side of the distributor go under the plastic washer and contact the metal of the points?

So is it like a pancakes - nut on top, then below it the condenser wire, then below it the plastic washer, then below that the other wire from the side of the distributor, and below that the points metal?

Any other thoughts on this?

Many, many thanks.

Check the braided wire from the connection to the condenser. Quite often they can fray and ground out especially when the mechanical advance rotates the point plate. This wire has to be free of all obstacles in the distributor, as it can ground, killing the points.

Tom,

Let's build-up.

Start with the post coming out of the base of the distributor points (with the threaded portion for the nut on top) with nothing attached or assembled to it!

Order of assembly:

* Slide the nylon sleeve down to the bottom of post with the flange side facing down.
* Side arced spring over the post so that the ID of the spring engages the OD of the smaller diameter of the nylon sleeve.
* Attach the end of terminal wire from side terminal of the distributor and place it on top of the spring
* Attach the terminal wire from the condensor and place on top of side terminal wire connector
* Now slide the other nylon sleeve down the post-smaller diameter facing down, flange "hat" facing up so that the OD of the sleeve slides into the ID terminals of the condensor side termininal connector holes.
* Attach the nut on top so that it is only contacting the top of the nylon sleeve and nothing else.

Hope you are now sorted but condensers have a bad track record of failure straight out of the box. So if it doesnt work at all after you are sure its fitted correctly, I'd suggest going back to your old one and see if you at least get that rough running fault.

Low tension lead, and condenser lead both touch the springy part of the points., than the plastic thingy on top (Notice shoulder), than the nut on top of the insulator. smileys with beer

I bet the points are grounded…..go to the top of the points where the condenser wire attaches and make sure there a plastic washer isolating it from the stud.
