In this video I diagnose my existing converter WFCO model 8735P as faulty, and replace it with WFCO model 8735AD. The upgraded model works with both Lead-Acid and Lithium batteries and so will be compatible with my RV now, and will enable me to upgrade my batteries to Lithium in the near future. I’ll take you step-by-step through the replacement project so that you can save time and money doing it yourself. Reminder; I’m not an electrician so this video will be valuable to “common folks” with basic handyperson skills.

From the start of the video to about 6:30 is the background of symptoms I was experiencing. From 6:30 to the end of the video details the step-by-step replacement process.
