Hello,

I have a prewar car. Ignition has double breaker points and double coils. I will need two kits to get it right. But that is not the problem.

Problem 1)
Disconnecting one of the condensors is a problem, The disconnection itself is not, but in case one of the kits fails (and they regularly do I read) reinstalling the condensor on the roadside is a huge problem. So can I modify the circuit in such a way I can leave the original condensors in place?

Problem 2)
As mentioned kits seem to fail now and then. The cure is seems to swap the main transistor for a more powerfull type. Any recommendations?

Capacitors must be removed for the kit to operate properly. No modifications.
Kits do not fail if properly assembled and used within specs. Thousands of happy users. Kit has been around for over 20 years. Only the ones with troubles can be found on this forum. This can give a wrong impression.

Thanks for the reply.

My comment on failing kits does not concern messages on this board. It refers to what I read outside this board.

If you want to make sure you don’t get stranded to the side of the road, I suggest you build a parallel system with two switches so that you can switch old breaker points to the ignition coil ground and bypass the K2543 kit if fails. With second switch you can connect or disconnect the breaker capacitor. It works nicely and it is always wise to have backup system if the primary fails for some reason.
