10MM terminal means nothing to me.
The terminals are Numbered. Which terminal are we talking about. I have your Schematic posted up on a screen right here.
15 is ign feed and 1 is EZL switching.
If there is a ground wire on the coil, it is NOT on a circuit terminal and if you put it on a circuit terminal, that is why you burnt up the feed wire.
The car will still run w/o a coil ground.. the ground is for RF noise.
