Help wiht my dead Chrysler electronic ignition

Can some one out there in Hot Rodders land tell me what to look for with my dead ignition? I have a fairly stock 70s/80s Chrysler electronic ignition. Distributor is curved but otherwise stock. Also have an MSD5 ignition box. Has run great for about 5 years 'til about a month ago. I went out to start it up one morning to go to work and had ZERO spark. Came back the next morning and it fired right up and has run fine ever since until it did the same no-fire thing this morning.

I plan on going out with my trusty multi-meter tonight and start chasing electrons (hopefully it will still be in failure mode!) but I would appreciate some opinions on what has gone south. Chrysler electronic module? MSD box? Other?

Willy's,
I had a dodge van back in the 70's that did the same thing when I was in college, but it was still under warranty and it was the electronic control module. About all I remember is it is kind of square and sat on the firewall with a single plug in it. Never had another problem after it was replaced.

Thanx. Yes that is my suspected part right now. Everything else in the system shouldn't act like that. Did yours stop and go more than once?

Yes it did and one it started it would be ok until it was shut off. I was going to school in Flagstaff AZ at the time and I took it to the dodge dealer as it was under warranty (Gosh that was a long time ago) it was back in 76 or 77. By the way I just read your post on the Mysterion and saw were you adapted the Ford window motors to the original window regulators in your truck, do you have a picture of the bracket you made? Thanks.

Thanx! I'll stop by Southern Auto on the way home and pick up another module.

Yes, I have several pictures of my window motor conversion. I'll send them when I get home tonight. Embarrassingly simple to do!

New Chrysler module didn't work so I'll try bypassing the MSD this week end. Will probably need to go thru the system with my multimeter afterall!

Send me your email address and I'll send the window riser info.

You can test the msd with the white wire just touch to ground. Do you really need the Chry Module with that set up?

Once you put a transistor in ANYTHING it is way beyond my abilities to understand. I just hooked it up according to the directions. I know now it isn't the module and may not even be the MSD, could be one of the wires in my harness which has melted together on more than one occasion! Test the MSD then go after the bad boy with my multimeter is my plan. Haven't had an electrical problem yet that can outsmart that combo.

Willys36@bak.rr.com. I changed from AOL to broad band.

Found my no-fire problem. It was the MSD. Also discoverd my distributor vacuum pot is bad so will change it too.
