I have a large voltage drop across the House battery disconnect switch. Almost a volt.
I found I can move the on/off knob slightly and reduce the voltage drop to 0. So the contacts are pitted or burnt.
Does anyone know what make model this switch is (I thought it was "Blue Sea") but they don't show this switch on their website. It may just be discontinued.
I'm not sure if the switch can be disassembled and cleaned - but if this switch is still available, I will just get one (then mess with the old switch). If I need to replace with something else, the terminals need to be in the same location. It would be a real project to try to reorient those short heavy cables. I can barely see the back side with a mirror.
Who makes this switch and what is the part number? Could this be the replacement?
