I realize this likely should go in the technical section, but I thought I would post it here first. My witness has stopped working, it is the 800 series, but I do have power to it on the meter and if I run a jumper cable to the battery ground there is a complete circuit.
A neighbouring boat who has some electrical experience thought maybe the ground had coroded, not allowing it to make a complete circuit. Does anyone know where these are grounded? I've been looking for it so far no luck. Thanks, Richie
