Confused - MSD Ignition Installed

[dkinworthy]

Hello All, I put a complete MSD Ignition system in my 72 challenger (73 wiring harness per schematic) My Problem is she wont run, The Brown wire from the ignition switch to the + of the coil would be the run wire right? the problem is MSD tells me i must maintain 9 volts while cranking or the system wont fire, I appear to be lacking voltage at the brown wire. she sputters but wont run. If I supply a wire directly to the ignition wire on the MSD box it runs fine. some have suggested the ignition resistor but i did not install one due to msd's directions state to throw it away. besides, per the schematic its basically just jumpers to the coil anyhow....:dontknow: so whats wrong?

did you connect the brown and blue wires (from your ceramic resistor) together. they need to be for the ignition to work of your key ign. switch.
