Guess I spoke too soon............go out to start my car today and no ignition check fuse box and blown fuse..........20+ fuses later and trying every wiring combo my friend and I can think of and still can`t figure it out. Turn key to crank position and fuse blows....I wired it right and now it`s all wrong. There was a problem w/the ign. when I got the car years ago and that explains why he bypassed the ign. switch and ran a remote switch w/activates the msd box THEN you hit the key to start it.........5-days later I`m beat and over this pos for a bit. How would one go about wiring up the ign. switch when many of the wires are gone and why the hell did it run yesturday and not today? Totally baffeling and I guess I realy have to earn this one............later.



You need to make sure that the "start" and "run" circuits are tied together, but not supplying the MSD with 12V at the same time. When you turn the key to "on" you should be supplying 12V for the "run" circuit. When you turn the key to "start" the ignition gets 12V from a different source while cranking. If you bypassed the key and have power to the MSD all of the time and you turn the key to "start" it will short out and blow a fuse. Sorry I missed you yesterday, got called out to work...

I am sure this is minor and it sounds like you are doing a good job by not letting it get the best of you.
