How do you determine what each leg on a 6 leg toggle switch is for?
Need more info. Model of boat? Try getting wiring diagram online? How did the switches function when they were working -- did each switch do the same thing, i.e. turn the same lights either off or on? In any case, you DON'T want to willy-nilly try running a new power lead without knowing exactly what's going on, else you may massively fry wiring, other accessories, switches, etc, or even start a fire. No getting around that you need to track (using a multimeter set to read 12 DC volts) from the power source (battery/alternator), along whatever wire(s) you think might be going to those switches (color coding of wires may provide clues), and determine where the break occurs. 99% of the time that will be at a connection, rather than in the wire itself. Do you have power at your controls/gauges? Check crimp connections especially, if you have any -- they can eventually die in marine environments. My guess is that finding and fixing one or more bad connections will get you lighted again. Use marine-grade replacement electrical parts from WestMarine/BoatUS/Defender/etc., rather than Home Depot parts.
