hey folks.
I just installed a new msd ignition box. Using the diagram for the msd distributer/blaster 2 coil/ msd ign. box set up i have everything connected right. I have the main red/black to the battery. I have the white wire from the box going to the orange wire from the distributer. The (smaller) red wire from the box going to the same wire i used for the tach ( only hot when key is on). I turned the key and it turns over right away and fast.... but no fire. Then i hear a buzzing sound ( kinda like an open door buzz) coming from the msd ignition box. I turn the key to off and the sound stops. If i'm missing something please let me know. I used two of the supplied connecters the blue guillotine style with the metal that cuts into both, for the white/orange and red/hot when key on wires.

thanks allot
