I just logged in to add a little something to the 6 pages of our friend with the 58 Chevy, no start. I don't see it now. This seems to be a baffling subject for those who grew up in the electronic/ computer age. Let's just add a few tips for the archives. Forgive me, because I just skimmed through all six pages. Maybe I missed this: The breaker plate moves with the vacuum advance. Therefore, it requires a ground strap. Fords were bad about the braided strap breaking. Chevy had a coated wire I think, but can't remember for sure. Anyway , it needs to be checked, and in one piece. Otherwise, the points won't ground and fire the coil. Also , when working by yourself, all you need to do is turn the engine over until the points are open. Then take your test light pick, and stick it between the open points, with the key on. If all else is right , it'll fire the coil every time. What else?
