How many volts does the secondary coil put out?

The secondary coil is putting out more than 60,000 volts and the plastic tube (inside the metal tube) is the insulator. We’ve seen multiple coils develop a small crack in the plastic and of course its arcs/grounds out on the metal tube. This type of failure will definitely trigger a misfire code.
