Mr. Bill Robertson: Nope ... I just removed the old original Bosch coil and dropped in the MSD coil, so the factory ballast resistor is not by passed. Yes, I am still using the factory ignition module, for there is no need change it. No, I do not know the voltage into the coil. I have not have the need to measure the input voltage, for I feel I need not be concern with it. Since it is only the coil I am replacing are R&R. I had consulted with the retail salesman about the MSD application in the PVR motor and the coil is a "simple" replacement which it was .... 20 minutes from start to finish including removal of the cover. I must say, it was the simplest, easy and the cleanest task. FYI.... I have no troubles with the ignition system. I do a complete cap, rotor, spark plugs and wires changes every Spring time -- Religiously! Do keep in mine I do drive my DeLorean daily in the New York City traffic and in the Northern New England area, in the hot and cold weather including heavy rain and in the snow. My engine kicks over within two to four turns with no problems at all in any temperature and weather conditions. My DeLorean has over 102,000 miles and still counting with the MSD logging on over 35,000 of it. And yes, there is a difference in the coils performance, I can redline the tach in 1st, 2nd, 3rd and 4th gear, but not the 5th. So....
