Has any one had this problem before. we went out last weekend everything worked great then we went out this weekend and my gauges wont come on like it has no power. the motor a Yamaha F250 2006 will start and run with out problem but the gauge stay off like no power when I shut down turn the key to off motor still runs, I must pull the safety kill lanyard to stop the motor. I checked the bus and it has power and seems to have power all the way to the gauges. any ideas before I go to the boat shop and pay out the hose. thanks in advance

gauge needs power and a ground to operate
key switch should send power to gauge on yellow.
key needs to ground the white wire to stop spark just like the kill switch

I would be looking at the ground if gauge gets power at key on

Update.
Bad ignition switch. Replaced the switch and all is good, gauges light up and function.
