Low voltage at the coil

[451Mopar]

When I read this, I was like the box is likely good, and the coil went bad (low resistance) or the ballast resistor / power to the coil went to a high resistance.
I like the "E" core coils (have a Crane PS-91 on the Charger), but they are hard to mount compared to the stock canister type. I have used the MSD Chrome coil, and haven't had issues with mine.

Sorry

Work got the best of me - I can’t spend all day on the Computer LOL

That’s awesome - When you said 1/2 mile and your results I suspected right away

Ask me how I know

Anyways

I have been preaching that for weeks - All this Chinese crap out there and piecing together a decent system today is like

These ECUs today don’t work together with certain coils

Also that Jegs coil has interesting specs with a 1.4 Primary and 4700 Secondary

And your testing wasn’t even close to those specs

Nope it wasn’t. Bought a new coil from Napa and took my ohm meter with me lol!

This is the one I got.
