Lights dimming, fridge clicking off and on.
My 2007 Mountaineer is my full time home. Bought it used last year. Just recently bedroom and bathroom lights will dim, which triggers the lights above the fridge to click off and on. I am new to this...

Usually what happens is the older single DC voltage converter/charger like what may installed in your 2007 year model will only put out 13.6VDC which over time will boil out the battery fluids... If this hasn't been checked and not re-filled promptly the batteries may take on internal failure and short out a battery cell.
Changing the converter/charger unit to a multi-charge smart mode model will usually resolve this problem.
When the internal battery cell shorts out the on-board convert/charger will really work hard to try to compensate for the battery shorted cell causing your 12VDC ceiling lights and other 12VDC items to dim and do strange things. Over-working of the on-board converter/charger sometimes makes that unit fail as well.
The first thing to do is check your battery fluid levels and get them at the proper fill point. You really need to start looking at your battery cells on a regular basis. I check my battery cell fluid levels ever two weeks even tho I very seldom see them needing maintenance any more since I switched to the smart mode converter/charger.
I use the PD9260C Smart Mode 60AMP converter/charger unit here for my 255AH Battery bank.
By all means like suggested above check the batteries first which may the culprit causing the on-board converter/charger unit doing the dimming your are experiencing. I too would suggest that you change out your older single mode on-board converter/charger unit is that is what you have. These became standard options on the newer trailers starting in 2012 I think it was...
You can check with Mr randy at BESTCONVERTERs and let him come up with a good replacement for your older on-board converter/charger. However don't let Mr Randy talk you into a WFCO product as many of of us have had smart mode problems with those units. The Progressive Dynamics and IOTA models are the most popular ones most of us like to use...
Having an inexpensive MULTIMETER around is a must have tool for making battery measurements. These can be purchased for $7-$25 from many places like LOWES-WALMART-Any number of auto parts stores, or ordered from AMAZON. A fully charged battery will read 12.6-7VDC at the battery terminals when not connected to shore power. When you plug into shore power this reading at the battery terminals will jump to 13.6VDC telling you all is OK with your battery system.
