Won’t start No Spark.

Thank you for the information. It cranked a little slower than it normally does when the car has been driven on a weekly basis. But didn’t seem low enough to not start. I didn’t build this car as it already had the MSD parts on it when I purchased it and it seemed to work well for the previous owner because it has been that way for a few years before he sold the car to me . ( First Mopar by the way now we have two!..lol ) This is why I went back to these components when it quit running the first time last summer Today I did jump the connector that triggers the coil through the box . As stated earlier. I would get weak spark about half the time. That’s straight from the coil wire to ground .But had no spark with the wire in the same position engine cranking. I checked both sides of the ballast with my meter and had equal voltage of both connectors .I feel stupid especially yelling at the wife when she said “ Does it need a new battery?” I thought I had read something about those systems being voltage sensitive.
