Not sure of brand. Small body and cap like point type. External gm type module, mounted under cover on outside of dist. Thought this might be an issue. But in my mind, module and dist triggers spark and delivers via plug wire. It seams to me, now correct me if my thinking is wrong, this would result in a no spark senario. I did check rotor button, and cleaned rotor tip and brass contacts in cap. Spark travels from coil thru coil wire to rotor button thru brass to rotor tip to corisponding term on dist cap thru plug wire to plug. The dist does trigger spark. So am I thinking correct?

Yeah, you're thinking right. The module is the trigger, and they either work or not but weak is not generally a symptom. Seems strange that a new coil would have the same problem, but then there have been some really bad experiences posted about Accel parts recently.

It seems to me that some component is not working when it gets hot.....could be electrical or fuel. I'd drop another distributor in there and see what happens. The modules will do that sometimes.

Yeah, I thought about this morning, and even though it's gonna be a pain I am going to pull hei dist out of my 66 this afternoon and drop it in. This will either eliminate electrical system or narrow it down to either dist, or coil. I would have rather not had another accel coil but they warrentied it. As soon as I can afford it, assumeing it's not another bad coil, I will try to get somthing else. So if you guys have any good or bad luck with a particular coil, round package type, let me know. I'll let you know the update later today. Good news dist is under warrenty, bad news, gotta come from tenn. Thanks for the help so far.
