Coil Voltage

Wow so much info. I have been a Mopar die hard for 47 years and I just took the ignition system for granted. Thank you all for the great info. Maybe I should leave well enough alone and start looking at plug coloration for a better picture. My goal is to make sure the setup I have is OK, especially since I am outside the box with a marine disty. Maybe post some pics of spark plugs?
