MSD issue
Ive chanced nothing electrical any time recent. The car has run since then. My electrical isnt very strong but here is what i found
The 2 wires blue and brown from the original system I get
Blue-0v in start position and 11v in run position
Brown-9.5 in start position and 0v in run positon
I did have the fuel pump running dead head off them which may explain some drop.
