I have a 1950 Chevy 3100 1/2 tone truck, with a 216 c.i. in-line 6 and a 6 volt electrical system. Externally mounted on the outside of the coil is what looks like a condensor/resistor. I managed to break the wire and am looking to replace it. From what I could find on the Internet, it appears to be a discharge resistor. On the end of the resistor it has a "D-R", a number "1910147" and the marking "3mf". I found some other Internet info that refers to it (or something else?) as a ballast resistor. My understanding is that it supports the coil at start-up and low rpm's. Anyway.... wonder where I can get one?
