I bought a Msd stand alone distritubutor 8388 and a blaster coil 8202. (eliminates the msd box). replacing a mopar electronic orange box system, which was acting up. Previous owner had the coil wires reversed, and the total advance of over 50 degrees, jumping in fast (been chasing gremlins for about 6 months now). Figured I would eliminate the ballast resistor in the process. found the ignition power wire to the ballast (blue) got 12+ volts when ignition on. all hooked up no spark. Checked power at blue wire going into relay for dedicated power to distributor when cranking, drops to zero. Not sure why the power drops from the ignition blue wire, I understand the resistor reduces the current to coil and points after cranking to extend there life, maybe an ignition switch issue, or am I thinking wrong on this? Thanks.
Hook up the brown wire with the blue.
Brown gives power while cranking.
