From: Las Vegas - Just stop perpetuating myths please.
Coincidence, everyone is posting 'bout bad 6AL boxes and not the 6 box.
Had a problem when starting my mtr after a 3-4yr shutdown. I have the MSD6AL, MSD dist with Blaster II also and found my power lead at the batt + was too corroded and not making electrical contact - no power to the box. Used that MSD troubleshoot guide to prove the box had no output - found corroded lead on a hunch. 
I'm running a MSD6AL for the rev limiter. Replaced my MSD6 box though still working.
While helping another forum member found his 6AL box bad too. Sold him my old 6 box and car ran fine again. Never found out what he did with the bad 6AL or what the problem/fix was though.
Ya know NASCAR rules require analog boxes (unless recently changed) and most those cars run 2 boxes. They can swap boxes at the flip of a switch.
MH, there are a couple of great books on ignitions out - 1 by Dr. Jacobs (Optimizing ur ignition) and another sold at Summit thats covers a broader number of modern boxes but sorry i can't recall the title/author.
But really too much to type here on trouble-shooting coils, dist's, plug wires, etc.. Its fairly easy and all u really need a multimeter.
Hope this can help. cardo0

From: Who says "Nothing is impossible" ? I've been doing nothing for years.
Thanks guys I will look at the troubleshooting guide and have contacted MSD
I'll take a pic of the rust inside the distributor, I noticed it a couple of years ago when it was not too bad, MSD said something about drilling a hole in the cap to let air in or moisture out or something like that and I told them they should be making these things so they don't rust, period
