So, I swapped an MSD 6AL and a conversion distributor into my car late last year. Some might call it a small body HEI. I bought it off a board member and it worked great for a while but now I'm getting an oddity that is confusing. For clarification, the 6AL is wired to the battery full time and it turned on by the ignition wire that normally goes to the coil in my case. So, if I start it and pull out of the garage and shut it off, it turns off. If I drive it to town and shut it off, the alternator light comes on and the car keeps running. I can open the door and nothing changes. When I hit the e-brake, it will die like I turned the key off. Anyone else seen anything like this? It didn't do it at first and won't do it until it has been driven a while. Could this be a ground problem? It is grounded directly to the battery. Could it be a capacitance issue that the e-brake light in the dash does something to? I've not investigated too much as it something I figure I can always remove if it get too annoying but I like a good mystery.
