Coil question
Is a Model A coil the same as a 50 Merc's? Obviously both are 6v.

Re: Coil question
Years ago I used the coil of my dads 55 ford to get my 30 model A started.I had to give it right back the 55 was our family car at the time.

Re: Coil question
It'll probably work okay, if its a good coil and If the resistance is correct. Early yblocks (54-62ish/6v voltage reducer inline to the coil) used 6v can coils and can be bought from local parts stores. Internal resistance is higher.
lot of maybes though... and the best thing about being wrong is you learn something. Last edited by Tinker; 06-30-2019 at 01:44 AM. |

Re: Coil question
The old originals likely had dioxin oil or something equally nasty inside to act as an insulator. The modern reproductions are more likely to be made with the same internal construction and materials as any 1.5-Ohm primary cylindrical can type coil. The can type coils generally don't need a ballast on 6-volt as long as they are no more than 1.5-Ohm. The later type coils for early V8 engines do need a ballast due to the design of the coil core and the way the coil windings had to be arranged around it internally. When they went back to the can types in 1948/49 they didn't need to use a ballast.
