I have a 1987 westerbeke 10 2 diesel. The alternator was replaced before I got the boat. The alternator is a Mitsubishi make. I don’t know the size. Attached to the rear of the alternator is i believe a noise filter.it is a small cylinder maybe 1/2” X 1 1/2” with one wire on it. The part has a Mitsubishi symbol on it and a number A 005. The wire broke at the filter.other than a filter it might be called a capacitor.i can not locate this part.there are plenty of capacitors that look similar but I don’t know how to tell if they are similar. Thank you in advance.
