Brandt

I have a 79 rx-7 with a 85 motor. Its been bridge ported . I just recentily bought. The wireing is a mess. It has msd. For some reason i dont get voltage to my leading coil and i only get 6volts to my trailing. And for some reason the msd is hooked up to the trailing coil. Since im lost i was thinking of switching to direct ignition and starting from scratch what are your thoughts on that.
