It is looking like I have a bad MSD unit (brand new). I've been over and over the wiring. I am only seeing .009v at the tach wire and MSD tech support says this is OK (Bob's docs sat you ned 1-1.5 v) . Either way I have no spark and no voltage at the small red wire from the MSD. MSD tech said to try a different coil (mine is a brand new Pertronix Flame Thrower II) otherwise the box is probably bad. I'll try a different coil but I'm 99% sure that is not the problem since I see no voltage at the small red wire (should see battery voltage here when the ignition is "ON"). I'll try to send the unit back to Summitt...using MSG Warranty services will take too long.

I probably should test resistance on the fuse...need to find which one it is.
