absolutely no spark and cant work out why - calling electrical whizzes

Thanks I'll give that manual a go tomorrow. I don't fancy putting it through my scope in case it decides to fire and fries it haha

With me having two cdi units and neither work I'm inclined to believe it's between the pickup sensor and the relay, if it indeed does more than supply 12v to the CDI unit. There's a few diodes in there I think are passing current where they shouldn't. I'm going to disassemble it tomorrow and test the diodes and resistors inside too.

Thanks, will update.
