So, I’m going to add some batteries to my 1991 Palomino TXL, which has never had them. I’m also going to re-wire and add a new power center while gutting the interior. This question is about “modern” power centers. My current, presumably original, power center has a rocker switch to switch between battery power and converter power, but the converters that I’m looking at online (such as this one) don’t seem to have one. Does this mean that the battery is always part of the circuit? That is, if I have shore power, the battery is being tended/charged, and if I don’t have shore power, then I’d be pulling my 12VDC from the batteries? If the previous is correct, then why the heck does my current converter have a battery rocker switch? Is it likely that my current converter is not a charger (given that the pup has never had a battery or location for one), and so this otherwise useless switch would be needed? I mention that this is a simple rocker switch, and not a heavy weight, physical battery disconnect switch. Thanks!
