Looking for any thoughts and opinions on a problem I have on a original 1934 Ford Tudor. It runs great normally, but from time to time it completely shuts off. It turns over but no fire to plugs. You might try again in 5 minutes or the next day and it will fire right up. Sometimes it runs fine for months before it happens again. It has a re-worked coil from Skip Haney, new condenser, new ignition resistor and new ignition switch block. Could it be a bad wire or ground? Just thought I'd see if anyone has had similar problems and what solved the issue.

sounds like it could be a bad condenser This message was edited by whizzerbug on 12-17-19 @ 4:04 PM

Check the input voltage at the input to the coil when this happens. It could be a bad ignition switch. Tom

Check all of the connections in the primary ignition circuit. One of them may be loose enough to cause an intermittent problem like you describe.

Sounds like a bad ignition switch. They get dirty and worn, but they can be opened up for cleaning and repair.

Any recommendations on a vendor for condenser? I'll check everything everyone has suggested. Thank you for your thoughts/opinions.

A failing condenser causes a weak spark. Check your spark before you replace the condenser. A sudden failure of the condenser could be caused by a cold soldered joint on the grounding strap, but you would not be able to restart the engine and drive the car with that condition. You don't want to introduce new problems by replacing good parts. You might have a loose connection in the primary circuit or a bad ignition switch, a voltage check will verify this or give you another direction to go in. Tom

hi I would make up a short jumper wire with alligator clips and jump the ignition switch contacts to see if that make a difference, out rule the switch itself, let here how you made out, my 2 cents 37Ragtopman

NAPA seems to sell the most reliable ignition condensers. I have to correct my posting above, the NAPA FA5 does not have the proper electrical characteristics for the 34 V8 Ford. NAPA does not make a condenser that properly fits, physically, the 34 without modification. I understand several distributor rebuilders use the NAPA IH200 which still needs modification to install in the 34 coil.

Thanks 40 coupe for the additional information. Thank you all for your advise.

Quick question. On the same car this is a photo of the ignition resistor on the left. Can anyone tell me what the electrical component on the right is? Sorry...…….I'm learning with this car.

That is a circuit breaker to protect the headlight wiring in case of a short.

Thank you 39 Ken.

You're welcome. FYI, this type of circuit breaker is the type that resets itself if the short is intermittent. So it's possible to be going down the road with your lights flashing. I had this happen once and it kept up til we found the short which was a bare wire loose enough to short on the frame. BTW, did you resolve the original problem of " ... from time to time it completely shuts off..."?

It hasn't cut off lately. I'll run it some this week and see if it happens again.

I would investigate what is going on under the masking tape on the wire going to the left terminal of the resister. It may be a problem waiting to bite you. Tom

Tom, I marked the wire with blue tape when I replaced the resistor...……..just haven't taken it off. Great observation.
