When our CMP shows "Chassis Battery Volt", it is displaying the house battery voltage. When displaying the "House Battery Volt", it displays the voltage of the chassis/engine batteries. Voltages confirmed by multimeter at the batteries. I accepted this as an oddity, but have recently been wondering if this switch may be affecting battery charging. I am understanding that the CMP only is a display and does not control anything. Am I correct? How would I go about fixing the display mix-up if I wanted to?
Thanks much!
