Hello all, I haven't been here for a long time due mainly to some personal hardships which are better now. I need ignition condensers for a '68 A65L. Is it possible to get some that will work from a local auto parts store. I found the Lucas part #54420128. I'm sure I can't get the Lucas stuff locally, but maybe something by another manufacturer such as Bosch, Daiichi, Delco, etc.? Thanks in advance for any replies.

Any condenser will work if it can be fitted, take the current one to the store and see which is closest to fitting.

Okay, I'm on the way to O'reilly's. That's what I was hoping for. Thanks for the quick reply.

The tin foil & tar caps have a finite life.
I would worry about any one that had Lucas printed on the side unless it says "made in PRC" on the card somewhere.

I used a couple of radio ones ......i dont recall the micro farhet (?) value of them but someone more electrically in the know than me could assist with that . The ones i did use were REFER brand which amused me (so dont fear the refer) , the are supposedly "self healing" what ever that means electronically .....anyway i put them in my A65 maybe 10 years back and so far so good .....best part was a packet of 10 cost about $5 from the electronic hobby type place

Since they only have a single strand copper wires coming out of them i mounted them in such a way that vibration wouldnt cause the wire to bust off

mine are mounted under the seat so dont know if the radio type ones would be practical if the bike has the capcitor mounted on the points plate?

another point is that they are also ok for using in magnetos ive been told

Use 0.22uf 400 or 630vdc MKT type capacitor.
You'll have to solder some leads on but they are a dollar or so and most are
better quality than automotive types.
