All nav lights out?

[kallanreed]

Hello All,
New owner, new member. Bought a 2009 34 Cruiser and I'm working through my punch list. I had it in for sail drive bellows replacement and when I got it back, it none of the nav lights (the ones that blink when broken) are working. The steaming light was known out and I was supposed to have that replace at the yard (they "forgot"), so as far as know, there wasn't anything electrical done aside from whatever needed to happen with the engine.

What odd, is that isn't only the monitored lights. The stern light is on a separate harness, the deck light (mast pointing down) works even though it's on the harness with the top, bow and steam lights.

I checked the Navi 20A fuse and that looks fine. Any thoughts on what could have happened or where to start diagnosing?

Hi Welcome to this forum and congrats with your Bav34!
Am I right your lights are being switched by Panel 301? Did you check the 5A fuses for the lights?
Do you see the power voltage from both batteries on the panel? Perhaps when working on the engine cables have been disconnected and power supply was cut.
Do you hear the relais ticking when you switch on the lights? Odd the decklight only works...
Check if the connectors at the back of the panel are well connected and if you do have power from the battery. Check connectors for any corrosion and poor contact.
If all power is available, measure on the contacts at the panel, trace the power from the panel to where it stops...
