Do the PCs come with a battery disconnect/selector switch so one may disconnect, select or combine house and chassis batteries? Also, is there master control panel for DC and AC breakers for turning various power demands off or on to cut down on parasitic electrical draws.
There is no disconnect on batteries.
There is a switch on the dash to allows the house batteries to charge the engine battery. When the engine is running it automatically charges the house batteries. BUT, the switch on the dash is a momentary switch which would require holding it on.
There is no reason I can see why this shouldn't be a normal on-off switch. I replaced the switch with an identical on-off switch which I bought at Advance Auto Parts. The switch pops out and has spade lugs so you just disconnect old and reconnect the wires to new switch.
WHY?- With solar panels installed that are for house battery. When in storage I leave the switch on so it is also charging the engine battery. I have done this for 10 years with no problems. One thing that is affected is that the step cannot be left extended using the switch by the door. When you turn on the dash switch the step goes in.
