RIP MSD 2 coil. Question

[slepysal]

So after cleaning and dressing up the old 250 I decided to go for a cruise. I go to start her and being the cold blooded beast that she is it cranked up and dies, no biggie....... or so I thought.
She just turnd would over .Oh crap what the heck ?Am I out of gas? Nope.
Check the coil no spark ! Now I have a pertronix ignition with a MSD blaster 2coil with ballast resistor, jump the resistor still nothing. Great!
My next door nighbor Fernando comes over to see what was going on. "What's wrong with your truck? It uasualy starts right up " ( he cracks up becuse his dog hates my truck's galss packs)
I tell him I think its the coil and he comes back with a new Accel coil" Here I was going to toss it"
Install it and she roars to life, sending his dog running.
Took Fernando for a little ride and stoped off at Jacks Liquors to pick up some cold Rolling Rock.
I get back in the truck try to start it and nothing !!! What the*&%? Fernado is sitting there cracking up and holding the coil wire !!
He puts it back in and she fires right up. Get home park it and crack open a cold one
So ( yes there is a question ) what may have cauesd the coil to give up the ghost?

Was the coil for points type ign. Or electronic? I had a points type that I used with a electronic and they didn't jive....

Or it could have been its time to go

I ran this coil for about 5 years with no problems... I think your right its time was up

It's been my experience that many aftermarket/racing ignition items do indeed provide maximum performance, but often the cost is reliability or a short life cycle.

The 2nd (and last) time I found myself on foot when my truck wouldn’t start, I went back to stock HEI components and have never experienced a failure since.

My Dad ran a performance yellow coil for about 35 years.
I took it out last year because it was too fat to fit inside bracket properly.
I've had other coils that lasted decades also.
If proper ballast resistor is used and coil isn't defective they can last a long time.
If coil gets too hot it can die.
You can measure primary and secondary resistance to confirm bad coil vs loose terminal connection.
Although common, I never understood the use of a stronger coil in a normal rpm engine.

Yeah Sal..the only coil that ever failed on one of my vehicles was because the oil leak out of it..
