Then ignore the instructions above, they are for positive earth Accuspark distributors.
Negative earth Accuspark distributors are wired as followed:
1. Connect black cable to (-/CB) side of coil.
2. Connect red cable and ignition feed to (+/SW) of coil.

Really important that the connections are correct depending on +ve/-ve, otherwise the unit will burn out, all as Ruairidh has helpfully provided. I think the Accuspark instructions for the positive earth connections are needlessly complicated!
Traditional coils will work both ways, but with a stronger spark if wired to the correct polarity (otherwise it is working backwards so not as effective/efficient).

Quick update from me.
It was a GOOD day.
Took my time and followed the simpler version of Ruairidh's instructions and with a few test drives around the roads to refine the timing, all was good.
Haven't tried hills yet but it does feel like I have more power at my feet. Time will tell but I am happy with today's work.
Thanks for the advice.
Andy
Enjoy yourself, it's later than you think!

ruairidh - please can you clarify what a soldered nipple joint is for the uninitiated, and why is it better than a ring going onto the screw thing?! I'm not sure if it makes it easier to disassemble, or...
