Hi guys, I'm rebuilding a 1969 A65T from basically a box of parts. I've got the engine in the rolling chassis at last and about to start the wiring. I thought I had everything I needed until I looked at the A65 parts book (1969) and saw there is a small capacitor unit in the ignition circuit, basically looks like two capacitors attached to a base and enclosed by a rubber cover and sits on the frame under the seat.
I don't have this and can't find one anywhere. Is there a modern work around? and what does it do?
thanks in advance guys.
ps my mates 1967 A65L doesn't have one although he has Boyer electronic ignition.
They are the ignition caps used for the points. Took BSA a while to understand that a hot shakey oily place is not a good spot to locate a cap. If you have fitted an elactronic ignition they are no longer required. If you are still running points they are required. Ask and I am sure there will be some one close to you with one sitting in a box since they fited their Boyer/ pazon/ etc.
The two capacitors are mounted in a rubber cover and are connected to the + side of each coil and one also goes to +, so you have four wires from the + side of the coil, one each to the caps the other two down to earth.
On '68-'70 A65, the condenser two-pack is mounted to a flat frame piece that runs diagonally across over the oil tank, under the seat.
There are only two wires to the condenser pack, one from each coil (+). They are grounded to the frame through the mounting bracket.
I think these condenser two-packs are available SOMEwhere, at least on this side of the pond. Right, you don't need them if you have electronic ignition. You may want to consider that, espectially if your auto advance unit and/or breaker assembly is not in good shape. Replacing those parts can be more expensive than installing an EI.

Wow, great information guys. Now I know they are condensers I can do another search. Also thanks for the info on correct way to connect to the coils. As you can tell I'm an A10 guy and not used to fancy electrics, give me a magneto any day.
