Nate,

Out of curiosity, what year/model Z are you trying to attach this alt. to? I know that zx alternators can be used on earlier Z cars, but in order for this to work, a couple things need to happen first. I couldn't tell you what they are, but a quick search of the site will yeild that info, should it be what you are needing.

Nate, I assume (from your only other post here) that you may be installing this alternator into a '73 240Z w/L28 ET. If so, my experience has been that the later 280ZX alternators have extra terminals that aren't used when putting them in the early 240Zs. The alternator I have in my yellow '71 is a little different looking than yours, but still has an un-used terminal pair on the back. I have the ones you list connected, and ignored the extras. Works fine, with the external regulator jumpered out of the circuit, and the diode (needed for early 240Zs, not certain about the '73) added.

Diode is needed on 73 also, just did one!
