2000 510 galley and bedroom lights shutoff randomly

[nickruocco]

Hello,

My 2000 510 has some issues with lighting I can’t figure out. Randomly my galley lights would turn off and the switch would not do anything. Then they would randomly start working again. This is now happening in the Vip guest room. The breaker is not tripping and the fuse in the light switch is good. What could it be? Are there any other components I can check?

thank you!

My bet is a ground connection that is common for both.

I may have found one issue. Not sure if they are related yet. I found a stuck GFCI in the cockpit. It will not trip and reset. I had that happen with the lights in the v-birth would not go on when the gfci in the head tripped. I will replace the switch and see.

Didn't realize the galley and vip lights you were talking about were DC lights.

The gfi is for 120 VAC nothing to do with 12VDC
