Starting problems
1946 Ford Sedan, all original. Engine starts easily when cold and runs great, no misfires, no fuel issues. After I drive the car about 20 miles or so and turn it off, it will not start again until the engine sits for a while and cools down some. I use the 20 mile example because that is about the time it will start to run oddly then die. It will also happen if I run the engine for a while, once it warms up and I shut it down, it will not start again until cooled down. I have checked the fuel, OK. Check the spark when trying to start it, seems okay. Thinking something is heating up, then cooling down but don't know what it would be. Would spark plugs do this or some resistors or the coil. Any help is greatly appreciated.

Re: Starting problems
Coil X2. Send it to Skip for rebuild.

Re: Starting problems
Sounds just like my 39. Ok cold start and short drive but then it just goes downhill. Had to push it back into the shop the last time I had it out. I believe the consensus is the coil is failing. I have a spare (also weak) that I should try or maybe just get one rebuilt and be done with the fooling around.

of that going on this forum and it keeps on with the exact same problem for years and reoccurs almost every week. Skip has been rebuilding 32 to 48 Ford coils for over 20 years and once his coil is installed the problem stops. G.M.

Re: Starting problems
Yep - do the condenser first . . . if that doesn't do it, then the coil. With that said - you can't go wrong with having your coil redone by Skip - he is the man!

Re: Starting problems
Listen to Bubba and it's the cheaper of the two, I have a 47 Ford for most part original and had same experience when heated up...

Re: Starting problems
Skip is Skip Haney at http://www.fordcollector.com/coils.htm
Bubba is Jim at http://www.lindertech.com/bhrs/ Both are great guys |

Re: Starting problems
I agree, the condenser is easier, and cheaper, to try first. However, get 3 condensers, odds are one of the three will be good. Or maybe that only happens to me?

Re: Starting problems
Yep - a lot of CRAP condenser parts these days. And don't make the mistake of thinking that 50 year old ones are probably good - they're probably shot as well.

Re: Starting problems
If anyone has a bunch of 32 to 48 coils I will bet them however much they
want to bet per coil that almost everyone will fail when hot. I have tested hundreds of them and maybe found two good ones. The Ford~Heyer distributor machines have a coil tester and provide a way to heat the coils for testing. Over 99% will fail hot. I believe this was a problem when the cars were new with some coils and due to the poor insulating qualities of the varnish used to coat the wire and dip the coils after winding plus the paper used between wire layers. Today there are wires coated with heavy two part materials that are superior for heat and electrical insulation paper between layers of wire. DuPont made papers such a Nomax and others that that provide better heat and shorting protection. I made coils and transformers in my manufacturing company. We designed, manufactured and tested the products. Large resistive load banks were used to heat and time test the the transformers. The Ford test machine does the same type testing. Skip uses these modern materials in his coils and does a heat load test on each one. Combined with quality materials and testing is the reason for the success with his coils. In over 20 years he has rebuilt over 20,000 coils, find me one of his coils in 20 years that failed and he didn't rebuild free. Condensers are tested cold first then heated. Most test good cold and if they test good hot then they are good. The coil and condenser are like your heart so why not have the best. G.M.

Re: Starting problems
Thanks for all the information. I did put in a different condenser I had from another distributor, it seems to be running okay and re-starting for now. I will be taking it on a long ride soon to check it out further. I have ordered some other condensers a spares. Hope this fixes it, it not I will try the coil repair.
