Yamaha guages, Question

[ttles714]

2001 twin Yamaha sx250 (ox66)...Starboard ignition switch activates stbd tach, speed, and fuel management.. port ign switch activates only port tach. Does that seem right ? When checking battery voltage, am I only seeing the voltage for the starboard motor ?

yes.
with the FMM you power up 3 gauges on one key, whatever key is powering them up is the one voltage is shown for.

thanks....this boat new to me.. still trying to figure things out.. I guess if I want to monitor battery voltage on the port engine I would have to install a separate gauge ? Or is there a wiring change i could make to toggle between each engine ? thanks for the help
