I think I have read something on this before but can't find it. I have two starting batteries that are old but seem to be ok with a switch that allows me to switch between batteries or use both of them. The wiring for Onix goes through a rocker switch on the console panel. When I start the motor, low battery signal comes on showing 10.3 volts and the Onix reboots or turns off completely. Wondering if it is the switch or batteries? It is a major undertaking for this fat, old cooter to run wiring from batteries to console.
