No power to dash on boat. There is no power to my panel and to my ignition switch and my boat engine wont turnover. Hello guys i have a 2011 sd188 ob. Went and got the truck and loaded the bu on the trailer and pulled it 10 miles back to marina. Only switch that still works is the master power and horn. The battery cable goes from the hot side of the battery to one of the posts on the relay and the power to the 50a breaker and whole dash is merely spliced off that same input post of the relay. I have a bayliner capri.

The relay could be completely blown and you would still get power to the dash. My boat has no power to guages or ignitionbatteries good red breaker will not push inswitch to change from 1to2 batteries cleanhelp.

New battery all fuses under the dash are good the 50 amp breaker on the engine is set. 1 hour later turn the key and no power at dash. This had come unplugged.

What do i need to do to restore power back to my panel. Put a meter from ground to the eye connection. On my boat it was a white connector with about 10 wires that was hanging right under the dash. Its also possible you have a buss bar connection that is just a distribution point to power the dash components. Can somebody please help a new boat owner. All others have no power radio bilge lights all gauges except fuel still work.
My boat has no power. On most boats under the dash there will be a wiring harness connector for all of your instruments and power at the console. Answered in 5 minutes by. Tow boat us got me for 210 to get me to a boat ramp 12 mile away. Ask your own boat question.
