First time poster & new Sea Ray owner!

I've recently purchased a 1994 330 EC w/out a generator.
It has a 3 battery setup. I'm guessing 2 are starting batteries and 1 is the house battery, correct?

I am installing a HEART 1500W Inverter/Charger out of my old boat. I plan to have that solely connected to my house battery.

Does anyone know if the house battery is completely isolated from starting batteries, even if the ignition key is on?

Does the isolater switch off when the ignition is on so that the house battery charges of the engines? How about if I hit the parallel switch?

Thanks for your help!
