Electronic ignition
( 1 ) Bower-Bransden electronic ignition unit
Many years ago I was told ( and I believe it was repeated quite recently) that with B – B unit installed, the condenser was not needed . It was suggested that the condenser should be disconnected –but remain in position should reconnection be necessary to revert to “ normal” running.
I have now found an article from B-B which would suggest that the condenser MUST remain across the contact breaker.!
Anyone care to comment?
( 2) DG –Nition and tachometer
Does anyone know of any problems, or is it possible to fit a Jaeger (3 connection) Tacho into a DG ignition (with Bower- Bransden dual output Coil) system. If it is possible, would appreciate wiring info.
thanks

Re: Electronic Ignition Queries
Fuzzyjohn,
is it safe to assume that you're referring to Boyer Bransden's ID unit?
If so, their fitting instructions are clear as to whether or not the condenser/capacitor shuld be retained in circuit.
"The unit can be used with engines having no distributor, ...this applies to most motorcycle engines.
The standard fitting instructions can be used but the condenser must remain across the contact breaker, not the ignition coil."
I've used Boyer Bransden units for many years in my own cars as well as those belonging to customers, always leaving the capacitor in circuit to allow quick and easy reversion to the 'standard' setup.
The life of a set of points has been as much as 100,000 miles with a Boyer Bransden unit fitted, although it has been necessary to adjust the points gap now and again to compensate for wear of the fibre heel on the moving contact.
Easy enough to check if that was required without dismantling, using a dwell meter.
Nowadays, I use my own home-made electronic ignition units, something which I put together 'just for fun'...
