... I wonder over the years how many mopar guys hooking up an MSD for the first time made this mistake. I know I did.
Wow !!!! I may have been the next victim... I COMPLETELY understand were you're coming from. And to think, I already have a ballast resistor that was "bypassed" for my Pertronix I was running on the car. I just followed the instructions and disregarded the ballast all together, thinking, as it has been eluded to, the 12v feed to the ballast resistor was ALWAY hot. Sort of confused though on the triggering when I ground the white wire and it working. Is it because I'm not sitting in the driver's seat going to ignition 2 and thus initiating the starter and thus, power on the one blue ballast resistor goes dead........ Lordy, if this is the cast, then I knew it, it had to be an easy fix. Guess when I get home I will attempt this once again. I'll put the ballast resistor I have back on ( that's had a solid wire soldered into place for bypassing ) and just "t" off one of the leads for my red 12v MSD feed,,,,,
crossing my fingers.......
Thanks for the input..

Yes it's because you're not turning the key. Thanks to Chip for posting this for me when I couldn't log in. I hope this solves you're problem. And yes I only know this because I did the same thing years ago.
Now, of course, curiousity will cause me to experiment. When I get home, I will put a test light now on the blue terminal plug I had for the 12v MSD feed and watching ( with anticipation ), the light go off when I put the key into ignition 2 ( engaging the starter ).
Thanks Chip...

In hindsight this all makes sense now. I recently installed a MSD 6AL on my friend's 71 Challenger R/T without a problem, fired right up!! Actually was sort of proud of myself. I thought my current problem with my situation might have been the distributor. Truth be hopefully known, now I believe it was the fact I made the ballast resistor a complete circuit by bypassing it in the rear with a solid wire. I overcame, unknowing to me at the time, the issue of the blue wire dying with the engine is cranking. With the bypass, the circuit there had a continuous 12v feed and thus, VAROOOM !! when we fired it up for the first time.
Almost home..

If so verify you have 12V at the switched source while cranking and when the key is released
This was the first reply to your thread.....But don't feel bad I think the ballast wiring gets everyone on the first time...It's something you won't forget the second time around,,,

WooHoo !!!! I put my modified ballast resistor ( bypassed with a 12 gauge wire in the back ) on the car and plugged the 12v MSD ignition feed into it.....
One crank, VARROOOMMMM !!!! and purring like a kitten......
Thanks everyone....... Now I need to figure out where I want to permanently mount the MSD box ( probably in the nose somewhere ).
glad it worked out! i would suggest in the passenger compartment, just to be safe. i have been going through a lot of issues with mine, that while not conclusive are most likely related to RF. mine is mounted below the battery tray, and i may end up moving it inside.

Hey MICKM, I was having all kinds of weird problems with my digital 6AL-2 on my hemi cuda. IT was driving me nuts. Sometimes it was fine next time it would act up. It was mounted in the car under dash on the passenger side. Tried everything. It turned out it was the tach! It was only a year old but I replaced it with an auto meter and all problems went away. After fixing mine I've heard of several others having the same problem.
Mike, was that your factory tach with no modifications? The new MSD 6AL's now have a gray tach lead....

Fix the problem and send back the MSD total waste of money on street car I have had three new ones all took a dump were fixed and worked and quit again or slowed car down by almost .4 of second. No more crap I will use Pertronix or even points until I can't get them any more and I keep a Chrysler electronic set up ready to go again if need be just carry dist in trunk In the last 10 years I have not more then I can say for the MSD and Mopar electronic Ignition. If you race and want all the toy's and like to try to find misses that appear and leave the MSD is way to go
wierd. i've had the same one in for over 20 years. never had an issue that wasn't my fault and i love the way it 'woke up' the car over a standard MP unit, orange or chrome!

herb has been pushing me to try disconnecting the tach, just haven't got to it. i will give that a shot, hopefully this weekend.
i have an aftermarket tic-toc-tac, and really want to run that. what if that is the issue? is there something i can do to still run that tach?

Sorry I don't know anything about that tach and if it needs an adapter or not.
