2004 Adventurer bathroom vanity light

[gpshay]

I am a little stumped right now ... No problems in the past .. coach batteries are dead .. connected to shore power .. all lights are working fine ... turn the bathroom vanity light on and no lights ? ... turn exhaust fan on and it works ... changed out vanity bulbs & no light .. I did notice on one of the clear bulbs that I put in ... that the element started to energize ... If I use a 12v electrical tester and place the positive probe on the center of the socket and the neg probe on the inside of the socket .. what reading should I get ..? thanks Glenn

Check the ground in the light.
You should read around 12v in the socket but the lights would be on if that was the case.

There are probably common electrical connetions between exhaust fan and lights. Check for a loose connection.
