Yu[p, the 70's were fun. Now about that coil. Good move, when they heat up they can break down. You guessed it right.Its all good! I don't see any of them being bad frankly. Oh, I had a 1969 Econoline 100 Panel Van that a painter had and my Uncle had a plumbing company he bought it to use it...but it would run about 30 minutes and die. So he sold it to me for $500 and didn't tell me about the problem. It died a mile from my house...sat for a couple of hours and started right up...I told my Dad I was going to replace the coil and he told me it was a mistake. They either work or don't work...$8.00 coil and drove it for a couple of years...put a bed in the back and customized it. Ah the 70's sure were fun!
