failure of modern points
Thought I'd pass my experience of yesterday along, since it may help someone else. (I've been reading some old posts about intermittent and complete failure of modern style points at times. I replaced the modern style points yesterday in my '31 pickup. Wouldn't start after, and I found there was a dead short in the distributor. Checked the small wire between the plates, replaced condensor, checked and rechecked - dead short still. Removed the points and took them to a well lit work bench and dismantled them. The plastic insulator looked fine, but what I almost missed was a razor sharp burr about .040" long on the inside edge of the small stud holding the spring. As soon as the small inside nut was snugged up, the razor edge penetrated the soft plastic, and shorted out to the bracket. I carefully filed the burr, put the points back in, and my old pickup fired right up. Then checked the old points I'd taken out - same thing. Apparently the manufacture, when stamping out these little studs, makes this burr. It's easy to look for, and readily fixed, but a real pain if overlooked.

Re: failure of modern points
I know that I had my share of problems with the so called modern points. It seems to me that the pressure has been on to use them for at least the last twenty years. Even if they can be took apart and fixed, I don't plan to ever worry with them again. Your info may help some that get stranded with them and that is good.

Re: failure of modern points
Sorry Benson - can't be any help on that one. No markings on the points. They came in a poly bag from one of the Model A parts distributors.

Re: failure of modern points
It pays to buy first quality points. Motorcraft, echlin, standard. I remember years ago I went to the store to buy points, and saw the motorcraft were foreign made, so bought some filco points, made in USA. The car ran worse with the new points than with the old ones I just took out. I went back and bought the foreign made motorcraft points and put those in, and it ran perfectly.

Re: failure of modern points
This old pickup has been with me 45 of the last 62 years. I may go back to the original setup - certainly have enough of them in my stores. (there's one box marked in my father's handwriting "slightly used" - if nothing else, I'l always keep the box out of sentimental feelings.) I went to the modern point setup to improve reliability. Not sure that has happened.

Re: failure of modern points
Hi Ed, so that's why the hood was up on the pickup when I dropped in to see you yesterday! Thought it might have been another cracked intake problem. glad you found the problem so we can look our spare parts over. Barry
