I don't think it would have a big effect on the cars value. It would probably be an issue in terms of concours points but since I don't plan on selling it or showing it neither issue is of much concern to me; however I'm not sure I want to go through the effeort to do a conversion just to get rid of the points...

Many old British cars get converted to a modern negative ground, is that something that would be detriment to the cars value?

It never dawned on me when I ordered it that like most British cars of the day it is a positive ground system. So the question is how do I hook this thing up? Do I just reverse the wires on the coil (red wire to - black wire to +)? or install as per the instructions? Or throw in the towel and stick to the points?
