Default Re: I-4 and SV Engine Non-Oiling Rocker Assembly

Yes, the factory gauge is electric and does require energy from the battery via the ignition switch in order to register. Beyond that, there could be an issue with the op sender which is threaded into the block on the driver side, or the wire running from the sender to the gauge, or the gauge itself. You could temporarily install a mechanical op gauge which would eliminate the potential electrical concerns and would provide a numerical reference that is quite a bit more meaningful than what is displayed by the stock unit. In the future, I recommend starting a unique thread for your issue(s) in favor of tagging onto a somewhat unrelated existing thread.
