I have a 1963 C60 with an alternator, not a generator, I believe 1963 was the first year of the alternator. The fairly new alternator doesn't appear to be charging so I am going to replace the voltage regulator which I already have a new one of. I have a 327 engine if it matters. The voltage regulator is located just to the drivers side of the radiator.
Now on to my question. The bottom wire on the voltage regulator is broke right at the spade terminal. There is a dark brown wire below there. I am wondering if this is the wire that should hook there? I have had this truck since 1972 and never paid any attention to the voltage regulator until now. I don't know if the previous owner may have cut this wire or a mouse may have chewed it off at some point. The three top wires are blue, black and red in that order with the blue wire being on the top.
Does anyone have a C60 or similar truck 1963 or newer with an alternator that may have a similar voltage regulator? With the matching color wires on top that could give me the color of the wire on the bottom terminal? Also would anyone know the purpose of the bottom wire? Thanks for any replies.
