archiecorry Report post Posted October 23, 2017 I have 2011 Serrano motorhome. There are two switches at door entry and two switches in hall, these control two lines of 3 lights. If both switches at door are on all lights come on and you can shut off from hall switches or vise a versa. If I just turn one switch of all lights go out except for two and the come on very dim. Any ideas what might be the problem. Thanks, AC Share this post Link to post Share on other sites
dickandlois Report post Posted October 23, 2017 AC, Welcome to the FMCA Forum ! With dim lights on with the one switch on, I would tend to think there is a weak ground, a corroded connection or a switch issue in the area of the front switches. Got to ask if this issue just started or if it has been there all along or if it was an intermittent issue for a time. Could you supply any additional information regarding Serrano coach size and a specific model if applicable and if any of the lights are mounted in slides ? Rich.
