48 plymouth coupe-- ignition problems. No spark. Sign In

Hello,

I recently purchased an old beat up 1948 plymouth coupe, I found it in a barn and figured I could have a go at fixing it up. I have a fair bit of mechanical ability and these old motors are so simple to work on. However I'm not a pro by any means the car is my winter project.

The motor is a flathead 6, P15. I changed the fluids and turned it over. I'm not getting a spark at the plugs. I ordered new wires and tested the coil. Its getting power on my ohms meter. But it's getting a very weak spark hardly any does that mean the coil is bad??

Also the coil was very very warm after turning the car over 4 or 5 times. Abnormally warm??

Any and all advice would be helpful thank you!!!!

Good trick........... ohmmeters don't measure power. They measure resistance.

Don't over think it. Starting fluid in plug holes if needed. Just get it to phart for you and go from there,

Right sorry like I said I am in no way or form an expert. I am getting a weak spark from coil and no spark at the plug. So starting fluid would not be effective without spark. The condenser Is functional also.

What do we have here.? 6v system or what?

Not sure how you are testing for spark and you don't know if a condenser is functional so put devise away and do some basics. Coil has spark but plugs don't? I don't buy that yet,

You might check the condition of the points and the gap. Also, check for corrosion inside the distributor cap on the contacts and rotor.
