Bathroom light fixture

[7ofus]

New to us 04 Roo 25bh and the only thing that didn't work was the bathroom light.
I took it down and found that the switch was rusted out so it was just the switch that was bad. Got a replacement switch but I'm wondering if this is fairly common or is this an indicator of another problem. Water is not coming through the roof so I guess it's from shower steam.
Is there a way to protect the new switch from corrosion or is it just as simple as keeping the fan running during showers.

Fan running? Probably but I believe you could also cover all contacts, after connecting, liberally with clear silicone.

You can use a dab of electrial conductivity grease, helps the contact and preseves unprotected metal.

X2 on the dielectric grease; carry it in the trailer and use on all connections.

Thanks. I will definitely do that with the grease. I know we'll keep the fan running but any extra protection so I don't have to hunt for a new switch will be great.

Hi,
I just bought a 2004 Surveyor 29 foot. Everything works except the bathroom light fixture. I opened the light up and both bulbs were burned out. I put in a new bulb and it didn't light. I removed the fixture, opened the wire nuts and put a VOM on it...no reading on the DC scale. I looked at all of the bus fuses and all looked intact.
I am worried about a short somewhere that may cause a fire. any advice?

I don't think you have a "short" to deal with, that's uncontrolled flow of power causing heat. You have an "open" circuit where the power can't get past a bad connection. In most RV's the overhead or ceiling lighting is grouped into circuits. Try to imagine which circuit fixture would be just before the bathroom light. Most likely your problem is there where the daisy chain is broken or interrupted due a poor connection. There may be 4-5 fixtures in the same chain, but as little as 1 or 2. Make sure you have checked all the fuses with a meter, not just sight. Best way is ground your tester and measure the output of all fuses with a meter or test light.

Thanks, Vince.
We will camp over the weekend at Coles Creek Campground, Lake Carlyle, IL.
I'll bring my better VOM, and take time to check each fuse to be sure there is power across each contact.
Concerning the chain...there is a power fan in the bathroom, and another light in the bunk room right next door. There was a leak in that area that I had repaired after I bought it. Perhaps there some corrosion around the connectors to the lights. I guess if I take each fixture down and look for a parallel connection that is corroded, that should do the trick, right?
Probably, if I put connected the neutral (white wire) to the light and then a 12 volt power line from half of the fuse, the light should probably work.

The temp connection yes, that will prove the fixture, good lead on the small leak. Its only 12 volt, doesn't take much to block the power flow.

Thanks, Vince. I solved the problem. I appreciate it.
