MSD problems

well I was back at it today. I am getting spark to a plug. I just stuck an old plug onto #2 wire and turned it over. It was firing the plug. I noticed the MSD 6AL box red light flashes a few times and then goes out when I turn the key on. I believe the owner manual says it should stay lit at all times. I currently have the brown and blue wire to the 12V red MSD switch wire. I tried running the 12V switch directly to the positive terminal on battery and tried turning it over on the starter solenoid bypassing the switch, and still nothing.
