I have a 99 ZX2 thursday on the way home from work my batt light came on .....figured with 200,000 miles altenator went out stopped at autozone picked up a reman.....put it on and it wasn't charging.....took it back and bought a new one put it on and it didn't charge took it back a got another new one still no charge ....I can't believe three altnators are bad.....checked all my fuses all good...checked all connections .....all look good....so what do you think?
Ohhh and that little one wire plug in what is it for......check for power at all connections with test light and only the center one where it plugs into reg has no power.
thanks Tony
