MSD Failure Diagnostic

Car came to a complete stop this morning as per my other thread. A brief check over showed that I had no spark that the plus, checked further back, I had no spark out of the coil...

From here on im not 100% sure how to check further back. I have a MSD 6A and Blaster SS coil.



Which of these wires should i be able to get a multimeter reading on and when?

Re: MSD Failure Diagnostic

Thanks mate. I found that not long after I posted. I suspect (and dearly hope) that the trigger wire from the dizzy is just earthing out somewhere, since is was just an abrupt lose of ignition.
