Dual Field Alternator Conversion - New Electrical Gremlins!
So I worked backward from the problem (which seemed to be at the coil). I ended up under the dash, which was strange to me since nothing was changed inside the car. Anyhow I found the dash voltage regulator to be "burnt". I think it was in a closed state which sent voltage back out to the engine. Once I removed the dash regulator, I no longer had voltage on the blue wire with the key in the off position.
