Troubleshooting Electronics

[RussWalters]

I just purchased a 2005 Crownline 206ls and there are some things that will definitely need some attention.

So far, I know there are some electrical issues that need to be addressed and I was hoping to get some feedback on how you would suggest approaching troubleshooting them.

What I've seen so far is:
Nav lights not coming on
Courtesy lights not coming on
Radio not working

Blower, horn, bilge all are working fine and the lights on all the switches work fine as well, so power does seem to be getting from the battery to the switch board.

Thanks in advance for your help and looking forward to being a part of this community!

I would first check the bulbs in the lights, then look for a fuse panel. If those all look good, you probably have some bad connections.

if you get to looking at connections, make sure all grounds are shiny clean - to start
