Lights dimming in Jayco TT

[robdnorm]

I have a 2012 Jayco TT that we are living in while building our house. I have noticed there are times that the lights will dim and then brighten back. When this has occurred the air is off, water heater is on gas only. There are two refrigerators that are running and two televisions. Any thoughts would be appreciated.

Charge circuit on some converters don't like bad batteries.
Locate the make and model of the converter and post.
Later model converter can run with out a battery, don't disconnect it until you know what converter and whether it can survive with no battery.
You have been checking the water in the batteries?

This happened to me in my Dolphin. My house batteries were bad, ended up replacing them. Lots of electrical gremlins can be traced back to batteries, make sure you check them every month at a minimum.
