Stupid Electrical Issue

A visual check to see if it's simply connected, or a specific voltage check? It sounds like it's a loose/corroded battery cable at either the block or battery (more likely battery terminals). Try remove and reinstall and see what happens.

Thanks for help guys. I already checked it on both the block and the battery. Would you guys rule out anything on engine at this point and focus on the dash wiring? Thanks again.

When you are reading power on your ignition switch where is your meter grounded at? Battery? Engine block? Should read the same at either place.

So after finally getting the boat to run right at altitude now this. '87 Nautique 2001. Out skiing having a great time tried to restart the boat after sitting for awhile...nothing...thought maybe neutral switch was off...that was okay. Notice that no dash functions are working, blower, horn, etc. Boat is completely dead. Back at home. Check power from battery to engine with multi-meter its okay. Ended at ignition switch that is getting power at both ends. Tried to skip that still nothing. No, idea what else it could be. Any thoughts would be great. Thanks.
