electonic ignition

If you already have the Boyer, then use that. Either will work.

Only thing to watch out for with the Boyer Bransden Micro MKIII is the fact it needs a good, strong 12 volts.

If your battery dips under, you’ll have starting issues, and nasty kickbacks.

Other than that, you’re good to go!

I would like to use a Tri-Spark for my 650ss but they seem to be for the Atlas and later. If you’ve managed to use one then I’ll be interested to hear how you got on. 

Yes, I used a Tri-Spark on a 650ss while I found a magneto and had it rebuilt.

I liked it so much, it stayed on the bike!
 

It made for a bike that was a piece of cake to kickstart, with zero chance of kickbacks and a superb idle.
 

Very happy!

Hi , does any member have a wiring diagram for fitting electronic ignition to a jubilee 1963 model , I'm starting to do mine this weekend as part of my renovation, I've nearly completed the 12 volt conversion , regards Dave

Hi Dave,

Would have been better to start a new thread rather than tacking on to another one.

Anyway, have a look at the attached. It is one I modified from  a Grant Tiller https://granttiller.com/

Is for a Navi but the same setup. Ignore the indicator bits.

Regards

As soon as you go electronic ignition (and 12V) on the lightweights you need 2X6V coils. The bike comes with these if you had the original 6V coils. The WIPAC coils have a 90deg HT outlet for under the tank, works wonderfully. (Lucas coils have a straight outlet-awkward) The Wipac coils last forever. Details of this are on A O Services.co.uk.

Hi,

The circuit diagram has an error, also it can be simplified. Will update later.
