My 450. Voyager fresh water monitor has never been very accurate. When filling needle would stick. A little tap and gauge would move. now it is stuck at about 1/2 a tank. Ran out of water today while taking a shower. Any chance the gauge is bad or is a sending unit problem. Any advice on either project?
Watch the video, should help you find your problem. My guess is a bad sender. Hope you can make the link work. https://www.bing.com/videos/search?q=how to test a marine water tank level gauge&&FORM=VDVVXX
