70 up charging system upgrade question

Hi Matt, yes it did fire up normally a few days ago. Now cant get it to fire. Measured coil +ve to batt +ve and got 10.34v. I thought I would give it a full 12V direct from batt +ve to coil +ve and it doesn't even turn over.
So it may be sparking, and the problem may not be electric supply to coil or ECU. Right?
Get a tester and you'll see.
