[Tiara Open] AC Operation

[Sapphire]

There is an inverter, but it's unclear at the moment how and what it's connected to, I have not been able to find the generator battery or batteries there are 2 house batteries under the large set on the bridge, the generator acts as if the battery is low and just clicks when you try to start it, and since I replaced both the house batteries it must be connecting to some other battery source..

With genset and shore power off, look at circuit breakers still "lit" (assuming inverter is "on") and you will quickly see what inverter powers.
My genset is started from house batteries, yours may too.
