Tach and Trim Gauge not working

[marty5030]

My Tach and Trim Gauge are no longer working on my 1990 Evinrude 150 Hp on a 19 ft Champion. Any ideas what may be causing it or do I have to take it in to fix it? I am good with cars, but this is my first boat so still gaining knowledge and iboats has been awesome. Thanks for any info even if it is basic.
Thanks

PS. They had been fine and then just stopped. Motor sounds good still while running and trim adjustment works too. Also Voltmeter and fuel gauge work.

Sounds like you have lost a connection behind the instrument panel, Marty. Could be a loose or corroded wire or a blown fuse.

I checked all wires and they seem ok and no loose ones lying around. Is the fuse box under the console the only fuses I have, or are there more? I also checked the ignition switch wires and they seem ok too.

Thanks
