    from Spring TX

    I've never used an MSD distributor before but the guy next door asked me for electrical help and I tried to assist, unsuccessfully, so I thought I'd asked the most knowledgable folks around --- you guys.

    Ford motor 351
    MSD billet distributor orange, red, black wires. Part number 8354.
    coil - standard, + and - marked

    MSD says to connect orange to -, red to + and black to a ground.
    Coil has + from electrical connection box, actuated when key is on. (no real ignition switch, just a pushbutton to serve that function). Original coil was MSD coil but marked for 6 or 7, this is neither. It

    Problem is no spark, no fire, no start or run (obviously).

    I felt they needed a ground wire from - to ground. When I put this on, I was able to read 12.x voltage across the + and -. Without the ground, there is no voltage across those terminals.

    He sent distributor to MSD and they said it was good to 9k rpm.
    Coil ohms were 1.3 across +/-. 4.5k across + and coil output.

    Can someone tell me what the appropriate hookup for this coil would be using this distributor?

    Many thanks.

    I have a MSD Ready to run on my flathead, my ground was bad, I had 12v at the coil but no where else. Once I grounded my negative of the battery better, ended up on the header bolt, I had all the juice I needed.
