Got a Zenith 15080, Ford part # F8JL-TA, with an electric choke. Removing the carb for cleaning, the choke terminal thumbscrew was seized and trying to force it loose I felt something snap inside the choke. Opening it I found fragments of a plastic stop for the terminal bolt head and two very delicate coils one of whose leads was ripped off. I gingerly stretched out a couple loops of the broken coil to fashion a new lead and used a blob of epoxy to take the place of the stop (see photo).
I don't really understand the operation of this electric choke but presumably those coils are heating elements. I feel a bit unsure about my hack but thought I could at least compare its electrical characteristics against spec. I measure 16 ohms between the terminal and ground, seems like that's the resistance of the two coils in series. I thought I saw the expected resistance in a troubleshooting doc somewhere, but can't find it now. Does anyone know what resistance a good electric choke circuit should present?
