2008 Smoker Craft Resorter console panel problem

[chicagorandy]

The console has 4 switches with 4 circuit breakers. Tilt/trim and ignition work fine as well as dash speedo and tach. None of the switch lights now come on, horn, nav light, bilge and livewell no longer function - they DID work fine up until last week. The panel has no ground terminal strip. The single blade fuse at the battery is new. No broken wires under the panel. Any ideas on what to check? I'm 'assuming' it's a common ground wire gone wonky? But I don't see one. All assistance greatly appreciated.

Could it be a bad ignition switch?? Though the motor starts just fine and power trim works. Kinda racking my old retired brain on this one.

Got yiurself a bad/ corroded or loose connection somewhere, probably a ground, but you gonna have to go huntin, could be anywhere!!! Got a multimeter??? Start checking the circuits and see where the power stops....not much fun I know.....

A quick update - PROBLEM SOLVED!!! After a couple days of wire tracing, multimeter reading, fuse checking, cable bundle and cable socket inspecting etc.etc.,etc., this morning I was following the fused wire from the positive battery terminal to a sealed branching - where that one cable became two cables. As I further inspected the sealed junction, the primary lead fell off into my hands. Corroded wire. Taking apart the shrink tubed joint revealed all three wires were corroded. A quick trim, wire stripping and proper joining and VOILA! - the panel and all accessories work 100%. Yay! troubleshooting good fortune and a lesson learned. Thanks to all for the good suggestions..
