So I stumbled on an interesting HEI phenomenon

No Ballast resistor on this one (or any of mine anymore), HEI mod done. Problem was the "battery voltage" was too low due to alt not charging. Interesting how it presented itself. I tried hooking up the old battery without the alt connected and it did the same thing again after charging it. With the new battery and no alt it runs just fine. Soo battery is bad and The old alternator didn't put out any amperage.
