    Default Main Voltage on G3X

    I am curious what others are seeing for voltage of the main battery on the G3X . I have always seen below 12v and figured I just did not have a strong battery. I just changed the battery to a new odessey and I have the same thing. I checked the voltage at the battery and have 12.7 and I have 11.8 on the Efis. A voltage drop should not exist. I am thinking the Efis has to be reading wrong. I plan to check voltage behind the panel this weekend. Once it is charging I have over 14volts on the Efis.

    I should have been clearer, I mean when the engine is not running.

    Iíll check mine when I get back in country. Does it matter if you have the IBBS switch on or off? With the master switch on, it will charge the IBBS battery from the main battery if it needs it and the IBBS switch is on. I donít know if that would affect the voltmeter though unless that just draws it down??

    That is a good point. I will turn off the IBBS and see if it makes a difference. That would be a big draw to drop an entire volt though. I will report back.

    Thanks, same for me. I wonder why it reads so much lower than the battery? IBBS on or off I get the same numbers.
