Have you checked the fuse for your finder? It is usually located within a foot or two of the battery but it could be within a few feet of the finder display. Did you install the finder yourself or was it installed on the boat when you bought it? Have you checked on both sides of the power cable? Is it connected all the way to the display? Try wiggling the plug at the display or go to where it connects to the battery and check to see it there is a good connection there. There could be corrosion at the battery that might be the problem. Hope that helps but if all else fails, you can run a new power wire to the battery as long as you have a fuse in between.
