I am having an issue with my MSD 6BTM. I am currently on my second MSD 6BTM now due to having a faulty one the first time. I cant help but think that this is due to my one wire powermaster alternator. Has anyone ever experienced issues when running and MSD 6 box and a 1 wire alternator?
My battery is trunk mounted and I had the alternator wire running directly to the battery and the MSD power feed of the stater solenoid + post. Charging system seemed to be good but my first MSD seemed to burn up, for lack of a better word. I could tell there was an issue becuase after about 5 minutes of running the tach would start acting erratically and bounce all over the place. Shortly after the car would cut out, the MSD box was really hot to the touch and the car would not start until it cooled.
Since then I have received a new MSD 6BTM and have reinstalled it, this time with the main power feed to the MSD directly from the battery as MSD states in the instructions, but I havent hooked up the alternator cable. With a fully charged battery the car runs perfect no issues with the MSD, rev limiter works correctly and the car seems generally happy. This just leads me to believe that the alternator may be the source of the issue. Does anyone have any input on this? This is the last thing I need to figure out before I can get the car out on the street and start tuning it.
