In all the Evinrude generator systems I have seen, On the regulator the Center Field connection is a 4 amp fused 16 gauge blue wire. The yellow 14 gauge armature wire is on the right, and the 10 gauge brown battery wire on the left. Usually the regulator is marked B – F – A. The Field and Armature studs on the generator are different so sizes so to theoretically be impossible to get wrong. (Don’t bet on it after 50 years) . . . 😉
