My MSD box has gone pop so looking to re-instate the original 3-pin CDI.



On the attached schematic the '3-pin cdi to coil' connection indicates that the blue/yellow wire A connects to Nr.15 on the coil - in my ignorance would I be correct in assuming that this is the +ve side of a black Bosch coil.

Likewise assuming the braided wire is connected to Nr.1 on the coil where on the engine would this wire normally be earthed to?

Any photographs of the actual connections to the coil and distributor would be appreciated.

Thx

Martin
