boyer bransden electronic ignition

(1/2) > >>

whiteylfc:
i've just put a boyer bransden kit including mini coils on my Phil Read Rep.All went on okay but after about 10 secs it cuts out so i cant do a strobe check on the timing....anyone else had this problem or can offer a solution before i rip it off and put the old bits back on.One of the 3 lugs that hold the base plate down had sheared off (old damage) so i'm not sure if the new plastic plate will vibrate too much on 2 lugs.

The Boyer system on my/Eamon's Dresda melted just outside Leatherhead.

I switched back to points...   It's all very well having original 70's exotica but the electronics in those days was definitely of it's time (I know - I was an electronics engineer at the time)

 :(

Don't have any experience with these systems myself being a confirmed points man ( if it works don't f**k with it is my philosophy ) but that doesn't help you. If its an unstable backplate ( which is a good theory ) you could try temporarily glueing a third lug ( or just a suitable nut or something ) on with JB weld. If it works you could make it more permanent perhaps by drilling through from outside, screwing just below flush then filling and rub down / paint to make it look nice?

If it is the backplate I would imagine it could also be hard to start as it moves about and puts the timing out, is that the case? Have also heard that battery voltage can be critical on electronic systems so I would check yours and perhaps give it a charge

my philosophy has always been "if it aint broke,dont fix it" but i found to my cost at the '12 I.O.M. T.T. that old h.t.leads and pouring rain dont mix....while i was changing the coils i thought i'd try electronic ignition.i've cleaned the battery terminals and it hasnt cut out since.i just need another pair of hands to help me with the strobe light.thanks for all the suggestions..

I fitted BB pointless ignition to my 750 special without any problems...ever. I also fitted Andrews high performance coils, silicone leads, resistorless plug caps & NGK D8EV plugs. When I installed the blue & yellow leads to the laminate back plate I used thread lock to stop the small nuts on the connector posts from coming undone.
