I've attached a simplified electrical schematic for my 2021 Oliver Legacy Elite II. This schematic will be "basically correct" for most Oliver models. The numbering and amperage ratings shown for the breakers and fuses matches the numbering scheme in my Oliver Owner's Manual.
I made this diagram because my Zamp solar charge controller stopped charging the house battery, and I couldn't find a good electrical diagram online, and the Oliver Owner's Manual didn't provide a decent line drawing. So, I made this one. (my specific Zamp issue turned out to be caused by a badly corroded terminal on breaker B1 ... which by the way, any auto parts store will have a replacement for this thermal-type breaker). I also realized I didn't understand how the AC and DC systems work together, so I made a single diagram showing both systems.
Often a simple diagram can be used to trace a myriad of symptoms back to a common component such as a breaker, fuse, or even the house battery. Or, to answer a simple question like "why does the inverter run when I'm connected to shore power"? (the answer is, it has to because the inverter is supplying power to the 25A sub-main that feeds all your AC loads except the refrigerator! And the inverter gets its power either from the house battery, or from shore power, or from the aux (generator) input).
I hope people find this schematic to be helpful.
