Last week lightning struck my 1986 Procraft 1750 bassboat parked on trailer at my home. It completely destroyed my Hummingbird 400TX and blew out my Nav/Anchor switch on my dash and ripped my windshield in half. I replaced Huymmingbird, windshield, and switch (no problem), but now none of my switches and guages work. I can make fuel guage, lights, areator,and bilge work by running hot wire to the master switch, but tach and trim guage will not work. Any suggestions??
