Condensor Part number.

Post by AlanBartlett »

Does anybody know of the condensor part number on the distributor, so i can try and track down another one, as today found it it had packed up and producing very tiny spark, now ive tested this by another one which isnt mine, so looking for a replacement. Part numbers would be useful for the car shop to scan through their books.

Do Jowetts have a habbit of playing up right when you want to use them?

Just out of interest do a snap survey. We are all busy getting ready for the National, how many owners are having problems today 9th of May. I suggest it will be an eye watering number.

Never mind the adversity, Jowett owners are overcomers, will see you there.
Compliments of the Season,

Crisis evaded, thank god for mystery spares you'd thought you'd lost.

Once again Alan's exploits have reminded me about a point that I had intended to investigate.

The distributor on my 1930 Long Four has a cut-away 'C' shaped section below the main body, where the condenser should apparently be mounted. It would slide into the cut-away from one end and be held by the 'C' section of the distributor body.

Now this circular cut-away is about 30mm diameter, so modern condensers - with the side-mounting lugs - won't fit at all.

My feeling is that in 1930, the condensers were probably much bigger in diameter as they would have used thicker dielectrics - possibly paper - and may have had a 'cardboard' external sleeve like the old fashioned torch batteries.

Does anyone know for sure what vintage condensers looked like?

If I am generally correct about the external appearance, I plan to make up a replica using a modern condenser and building up the outside with laminated waxed brown paper, with end caps to look 'original'.

In passing - isn't it strange how we happily refer to 'condensers' when in electronics circles they have been capacitors for ages!

I always get confused on what to call it, condensor, capcitor, or in recent experiences crapacitor, what exact shape is your condensor mounting? with a couple of mine it screws directly to the points table via a brass screw. On another on it slides into a metal cylinder shape attached to the points table and is screwd to the non spring points side.

Alan: -

The condenser on my distributor is OUTSIDE the body of the distributor, just under the 'neck' where it narrows to fit into the back end of the dynamo.

The recess is machined cylindrical but because of the 'neck' it is not a complete circle - hence my comment about the 'C' shape.

I have a feeling that your engines are a few important years younger than mine, with a large number of technical improvements.

If I get any further with this, I will try to put a photograph to help.

Thanks for the reply.
