HEI Coil keeps going out, Please help!

Hi All,
This is my first post. I have a 68 Camaro but the question I have is on my dad's 62 Chevy 1/2 ton P/UP. In one year it has gone through 5 Coils. They go out while the truck is parked and not in use. Just drive it in the car port and park it and next time he goes to drive it it just cranks over and no spark. Put in a new coil and it fires right up. Could this be something wired wrong? The HEI was put in new w/new engine 1 year ago.

10 to 1 it's missing the ground strap or wire that grounds the laminated steel part of the coil. Usually blows the coil or the module when it's missing.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.
