Ignition woes (Again) Burnt Coil?
So I was finishing up the transmission job, took it for a short ride and it performed perfectly. I guess I solved that jumping out of 3rd gear Problem. I parked it in the driveway.Came out from cleaning the garage to put it away, NO START. What the hell is this, No spark! I was just down the road with this about six months ago, thought I had it fixed once and for all! I guess not! So I get the meter and check the coil. Now as I understand it, I should have voltage on both sides of the coil. I have voltage on one side only. Did I burn the coil?

Key off you will have voltage at both sides of the coil or key on and the points open |

Re: Ignition woes (Again) Burnt Coil?
Tom, I printed out your punch list of problems, went outside to where my coupe lay dead in it's tracks, checked both sides of the coil-OK. Next I took the cap off the distributor, put paper between the points and the arm was hot (6V). So just for the hell of it, I tried starting it again. It made one turn of the starter and fired off perfectly. So I seem to have a "won't start when hot", problem. I never had this before, what is the usual cause of these? I seem to recall it being a coil problem. T.I.A.

You need to check things when the issue is happening.

I've never had a coil or condenser fail. Never. I know it's possible, but it seems that every Model A problem here is blamed on the coil or condenser (or, of course, crap gas ) . I sure wish I had the coil and condenser concession here. I'm sure there are a whole bunch of coils and condensers that have been replaced prior to the owner doing actual trouble shooting and correcting the actual problem.

Re: Ignition woes (Again) Burnt Coil?
Dick, My experience is similar. I'm 72 and until recently, all my cars were point and coils too.
But, I have three mod. A condensers that are bad. How do I know? I have a condenser tester and they were the cause of my points not firing at sometime in the past. I'm saving them for who the heck knows why. Six months ago, I had similar problems and I chased it to a shorted plate. That was what is so frustrating, Is this car cursed? Furthermore, in my dotage, I can't get a mental handle on how the mod.A Ignition system works that will stay with me longer than ten minutes, maybe fifteen. Problems for me seem to evolve. sometime today, I will get the engine hot again just to see what happens. Wish me luck! Terry |

Re: Ignition woes (Again) Burnt Coil?
I had an intermittent "open" the other day, turned out to be weak spring pressure not pushing the movable points arm end against the power post.

I had an armored cable go wonky. Worked great, then out of the blue nothing, then it work again. Drove me nuts for a while.

Re: Ignition woes (Again) Burnt Coil?
I hope not! I bought the top of the line ignition switch ($ 55. IIRC) on Mitch's recommendation, during a previous bout with this thing. (That was before the last go around with the shorted dist. plate)
