No spark and i can only get 5V at the coil.
there are some 45 year old mopars out here with good original wiring. like my 1970 vs29h0 Duster, I am the 3rd owner, bought it in 1981 for $1000. all original unmolested wiring, original alternator, no problems. then there are cars of all makes that have been owned by monkeys
Here's the thing. LOTS of guys on here have had Mopars with original UNhacked wiring, but it had bad connections, burned, overheated, corroded, etc, and these are typically in the bulkhead connector, the ignition switch, and the headlight switch. Followed by anything else you can name, including heater / AC and TS switch.
If all you guys wanna do is throw parts at it, you need not have experience, knowledge, or any real troubleshooting ability. But you WILL have to have a lot of money, because you will be spending a lot. Worse, sometimes you throw a new part on, with a so-so connector, and it works---for awhile.
And if that's what you want to do, you don't need this board, or people who really do have an understanding of how these work.
And......they don't have to be old, either. "In a previous life," when most of you guys PARENTS weren't of age yet, I was harrassing people in San Diego in a 64 Dodge, or 69 RR, or a 70 V code. In other words a hell of a long time ago. The 70 bulkhead connector gave me trouble when the car was less than 5 years old, and certainly had never been in the rust belt!!!
There IS a time for throwing parts---when you are really really stumped, "best guess." Sometimes, that actually works.
