I have searched around on the forum, but couldnt find the specific answer I am looking for. I am trying to make the factory "battery" charging gauge functional. I have eliminated the voltage regulator and ran a wire from the alternator to the gauge, but before I hooked that wire up to the gauge I checked the cluster and their is constant power to both terminals right now. Where do I start with this thing? I am assuming that there should be switched power to one side and the wire from the alternator on the other side? Any suggestions?

Thanks
