1939 Six Overdive

Posted by jwblazek On 2017/2/1 20:39:00

I have a 1939 110 / six with overdrive. This was my Dad's car and for years he thought the car was stalling due to vapor lock. He rerouted lines, replaced them and finally put in an electric pump. I am now experiencing this stalling, very intermittent and at any outside weather temperaturs. Car will stall, at any speed, including just idling. No misses, just like someone turns the key off. There is not a ballast resistor for the coil, but as I look at the schematic, the overdrive switch, relay and other components are in the 6V path to the coil. I am now suspicious the problem may be within the overdrive circuit. Anyone have similar experiences or suggestions?
