MSD install, quick question
 

Intalling and MSD 6al onto a carb converted 3.0SC engine. Two quick questions. On the coil it's marked A and B which is + and - ? Is A + and B - ? As far as the distributer goes it has a shielded type wire is the core + and the shield - or the other way around? I wired enrything up so I could switch them if necessary but I'd like to know for sure before I try to start it.

Problem solved thanks to emcon5 ;)

I had both sets backwards. B goes to +, A goes to -. The shield is + and the core is -.

Thanks again
