If it is a WFCO it was a fail from the start. Voltage will tell.


I must have the only WFCO on the planet that still lights the lights, slides the slides, jacks the jacks and charges the batteries. ORIGINAL 2009 equipment. How lucky am I?

The thing is the voltage on the battery will be the charging voltage for quite a while after all charging has stopped. Could be 8 hours or even more. This surface charge effect means voltage method is at least inconvenient. A battery monitor that measures the energy in amp-hours flowing in and out will indicate the % of full charge all the time. There are battery monitor discussions on this forum ranging from the $30 eBay ones to top of the line.
I am very happy with the eBay one: https://www.ebay.com/itm/DC-120V-100A-Battery-Monitor-State-of-Charge-Remaining-Capacity-AMP-Voltage-AH-/182147916411?hash=item2a68dca27b:g:gWUAAOSwyQtVz1vp
This link to seller Elite Element includes a new type of monitor with wireless link to the display and simplified wiring. Here is a link to the RV.net discussion on it: https://forums.goodsamclub.com/index.cfm/fuseaction/thread/tid/29798122.cfm

You should get a meter if you want to see the actual voltage.

Looking at our monitor I noticed it was not what it ussually showed. One of the 4 batteries was hot and one cell was dry and stream came out when the cap was removed. 4 new batteries installed. Would be five years old this December. Always good to paid attention is my motto.
