Battery location: 1993 Jamboree Searcher

House battery will be on the drivers side - chassis battery on the passenger side. On the firewall (above and to the left of the House battery) will be a silver solenoid battery isolator - that solenoid should make a click when you turn the ignition key - when the engine is running it puts both the chassis and house batteries on-line/parallel which allows the alternator to charge both batteries. In a rig that old the converter will not charge the chassis battery unless you add something like a Trik L Start.
