Hey guys quick question hopefully i can find a proper replacement.

Alternator took a dump on the boat last season so took it apart to see what i had and replace with a newer better one.

Its off a 1994 hardin marine 454.
Original alternator is Prestolite 8em2002fa
37amp
12vn

Only wires connected are positive output and i noticed it also uses an exciter wire.
 Which is what is confusing me everything new i can find has more amperage but cant find any with an exciter wire terminal.
Most say single wire alternator. Is the exciter wire needed or can it be bypassed or not used with the newer self exciting alternators?

Just looking for a suggested replacement hopefully that will work.

Hey guys looking for some help. Getting things ready for the summer season and doing some maintenance and i need help finding a sterring cable for my boat... the cable in the boat currently has numbers on it saying MORSE 300624 180IN. To my knowledge morse is not around anymore and i am not sure what the cross reference brand or part number would be. All help in appreciated, thank you
