my nightmere (msd)

Hey Matt, this might be a long shot but when I started converting my old 440's with dual point ignition over to the Mopar Orange box electronic ignition the first thing I had to do was replace the old voltage regulator to the transistor unit. In effect it brought the battery voltage up to 13.5 volts which according to Direct Connection was required for the orange box ignition. Is there a chance that the MSD ignition requires 13.5 volts instead of the 12 volts you say you've measured at the battery. Also, if you haven't done it already connect your power to the starter, this keeps the wire length to a minimum and voltage drop, which is always a concern with long runs of wire, will be minimized. You say you've got the battery in the trunk. When I did that I used the heavy welding cable run inside 5/8 heater hose (stops rub-through) again to minimize voltage drop.:evil2:
