Many thanks Rob - knew you'd have the info ! I'll leave the redundant ICU in place just in case I need to revert back to standard ignition.
Yes, the little loom of 2 cables to the BB modified beancan are very obvious and no probs there.
Coils are in series.
You don't need the Boyers fused wire on BMW's. In fact if you use it the bike wont stop when you kill the ignition.
There is no fused wire on my loom from BB -or do you mean an existing BMW wire ?
My problem is that the BB Kit is fine, and pretty straight forward, but the existing wiring on my twin plugged PD is a bit confusing. Work was done before I purchased the bike, by Andrew Sexton.
My confusion is with the black wire I need to remove, and replace with the Black wire in the BB loom. Brown is no prob.,-that as you say, is the ground,
the green I think links on the coil terminal to the existing green (from the ignition switch ?).
The problem is which black wire I
remove - there is a black wire joining the 2 Dynatek coils in series, ( so it won't be that one ), one black that goes to the tacho, ( so doubt it's that one either!), but NO idents on the coils themselves, so I can't be certain which is the equivalent of BMW's "+15" and "- " terminal, so makes it confusing !
The wire I need to remove ( and replace with the BB black) is, I think one that comes from the ICU unit, hence my request for details of the multi-pin connector idents.
So apart from that, and another problem that took Dave and I a couple of hours of head scratching, ( if you accidentally remove the live wire to the starter solenoid, ALL power to the bike disappears, apart from side lights, and stop light ....!) - well you always learn something new !
Cheers Rob - see I did listen to your advice in that cafe in Belgium
