Im planning a Pertronix conversion. I spoke to Jeff at Advanced Distributors and he recommends switching to a coil with internal ballast. My J-H has the resistance wire instead of the little ballast box by the coil. The resistance wire connects to the white wire from the tach underneath the dash. I was thinking I'd replace the resistance wire with regular wire to get the full 12V at the coil. Any idea if the tach will work (or burn up) if I do this? A friend said his tach burned up after doing something similar. Thoughts? Would it be easier just to stick with the resistance wire? Thanks!
