I have a 2000 FR Sunseeker 23.5. I have the isolator switch on the drivers seat, but It doesn't work, nor does the house battery charge while I am driving. I cannot fine the isolator solenoid after looking all over for it. I decided to do a seperate smart battery isolator (off brand) the installation seems simple, but I am not sure what size wire to use to go from the start battery to the isolator and from the isolator to the house aux. battery. any suggestions?
