After learning about the WFCO issues with auto detect, I checked out the charging status of my 2023 tab 400 with the battleborn 100ah lithium. The led was ‘green’ and the charge voltage limit was in the 13 volt range versus recommended 14.4v.
So, I wrote to WFCO and got the ever friendly Shaun technician. He asked me what my software version was, and I could not find it anywhere on the face plate of the charger, even after multiple suggestions from Shaun. He then, oddly, offered that I should not have any problem with my auto detect. I wrote back that I really just wanted the jumper solution based on the forum experiences I’d read from many. Doing what WFCO recommended, didn’t seem to make it sticky to a lithium charging profile. Shaun replied that he’d ship a jumper out that day, which he did!
Picture attached. No instructions, just the jumper. I guess my email confidence implied skills with the converter. There probably aren’t that many six pin connectors on the circuit boards, right? The shrink wrapped jumper appears to be a resistor folded in half and pressed into the blade connectors of locations 5 and 6 (marked) of the six pin plug. I didn’t cut off the shrink wrap, but would if asked, before I install it to benefit others with the AD issues.
My only question is whether there are instructions for jumpering the 8955-AD. I recall instructions for the 8755, I think.
Thanks all.

For fun I searched the WFCO literature for PCB images of the 8955-AD product.
The best image (below) has One Six Position Connector location = = J4 = =
Image however does now have the Header installed, mate for the Jumper Plug they shipped you.

I have no idea.
Suggest you open-up the Power Center and inspect the installed PCB . . . it might have the socket.
If not, take a picture and send to WFCO support person that provided the 'jumper' and ask for guidance.
Let us know what you discover/learn.

Maybe they will put a darn Switch back on the PCB.

Step six: slide the converter back in place and secure withe the two screws. Step seven: Turn on 12 volt power and check for blue light. Step eight: replace and secure the trim cover.
Total time to complete the jumper insertion (converter to Lithium) 10 minutes

Thanks for the install details. Easier than I’d ever hoped! Will try it soon. Love that blue light.
