My dad’s boat appears to have all its gauges not working, including power to fish finders. However master power switch works, as does ignition, running lights, black fishing lights (he is a Center Hill night smally chaser). The boat still runs great (only 150 hp I have ever seen do a legitimate 70 mph GPS...guess those Johnson Fastrikes are a bit under-labeled), but scary not knowing tach, trim height, water pressure, etc. I have not had an opportunity to get under dash and really check fuse block, but when I do was curious if anyone had a sort of troubleshooting checklist I could run down. He stores boat under cover, under roof, though outdoors. Last time I was at his house I took flashlight and followed wires making sure no mice chewing issues or anything, and trolling motor harness as well as onboard chargers working just fine. While I certainly hope it is just a few blown/old fuses, any help or info would be greatly appreciated. Thanks
