Hei conversion troubleshooting

With key in run, Multimeter from battery positive terminal to VR terminal, I'm showing 1v. Unplug the VR, voltage drops down to normal range. With car started, it drops to 0.8v. What could be causing this huge drop? I spliced the 4 ballast resistor wires together, I wonder if there is an issue with my splice. They arent all 4 hooked together, its 2 and 2. Should it have been all 4 in one connector?

Just so you know. the coil body does not require grounding.
I would run a 12v wire direct from the battery+ to the coil+ and module+ and try it that way.
This eliminates all the old ballast wire questions and gives a known good supply with nothing to cause drops.

Also when swapping to HEI I tie all the ballast wires together at one point.
Usually ign1, ign2 and the regulator (sense) wire blue, and the new coil+ wire.
