I don't see any center tap. I see 4 tabs and also 2 leads that connect to the voice coil. I get 250 ohms continuity between first set of tabs and no continuity between the other set of tabs. I presume this set is the field coil connection. I do get continuity between each tab of the first set of tabs with only one of the other set. This continuity reads 7 meg resistance.
