It seems that the coil wire for some reason drops to 0.33 while cranking. Like you said the MSD wont work with this but it is the wire i need to use.
When i use a jumper wire and connect the coil wire to an ignition on wire on the ignition switch then then the coil wire drops to 6-7v and there is a spark, great! but obviously a jumper wire makes the usual ignition on wiring come on with Accessories (key on).
Is this something a MSD ballast resistor will fix? if so how do they actually wire up a ballast resistor?
Thanks again for your troubleshooting
