    stuck power relay. Look for two relays hanging from wire harness behind switch panel. Note which wires go to which terminals before you unplug them. Make sure to hang new relays with terminals pointing down to prevent water collecting inside. Replacements at any auto supply.

    Did you check your master battery switch? usually located very near the battery.

    Steve. So nice of you to respond. Yes I looked for one when I first saw issue but there is no switch by battery. Just traditional terminal cables and nothing I can see like a switch. It's 2013 188sd. Embarrassed to not know answer but master switch and all switches in off position but orange horizontal light still on switch itself. All my accessories work even if master switch in this down position. Main concern is just am I draining battery. Obviously don't want to disconnect battery.

    Is your key on?  My depth gauge powers on with the master power off and the key on.  Also, I would install a battery switch if you don't have one.  It will make sure you don't drain your batteries.

    steve_cady...turned out to be a corrosion issue causing it...terminals were on last leg...actually glad i looked into it bc that master light issue was the only reason i went to look at the wiring.

    The issue was the battery terminal or the terminal on the power switch itself?
