It is the regulator with a triangle connector and it has a blue wire and a green wire coming off of it. The alt has the large stud for the battery and it also has two male connectors. One is marked GRD and had the green wire attached and the other one is marked FLD and had the connector that has a blue and also a dark blue with white tracer on it. I am not sure about the continuity readings. the GRD terminal will have continuity with the case of the alt because the male terminal is screwed to the case. Where shouldn't I be reading continuity, between the FLD and the GRD terminals?
