i have a professional mariner battery monitor that is old. it has a 4 position knob for batteries, a led window and on/off.....the red and black 12v power wires came off the back because the wires were tight and worked loose. i need to know what number position the red and black go back into. there are 8 positions. professional mariner has not replied even after several requests so hoping someone will look at theirs and let me know. kindly.
