My 1938 Ford flathead refused to start yesterday. Problem no spark. Upon researching I found that the little spring tit that goes from the coil to the points was melted. Now here is the problem. Sometime someone as installed a conversion to a regular type coil on it. There is a plate that bolts where the original coil was in the top of the distributor that resembles the bottom of a regular coil. Little spring tit with the condenser and secondary winding wire attached and the tower like rotor terminal where the high voltage wire from the coil attaches. I can find no reference to this type of conversion anywhere,. I'd like to replace the part if I can find it. Any one ever seen this type of coil conversion and where did it come from? Where can I buy replacement parts? OK! now that I got the pictures posted. What caused the spring tit to melt. I do not see a ballast resistor anywhere nor do I know if the coil has a built in resistor.
"What caused the spring tit to melt. I do not see a ballast resistor anywhere nor do I know if the coil has a built in resistor." Probably running 12V, too. That'll definitely melt your tits off. You need 3-4 amps ... via a proper resistor. Use your ohm meter to measure the resistance across the +/- terminals of the coil. Divide that into the volts you're running. Add whatever resistor is needed to drop down to 3-4.
