Chassis Battery "AGAIN" not charging

the last 2 hours I have gone over older threads; even mine. about 1 year ago, I changed out the trombetta. all seemed to be working fine. go away for the holidays, and come back to a dead chassis battery. there is no throughput to the battery to keep in charged. This was working just fine a year ago.

while checking the 5 amp fuse, I noticed that all of a sudden, the radio inside came on. very weird. also I noticed on the schematic I have that the yellow/blk and the white wires on S2 and S4. on the rig it is the opposite. Now, I am not sure if the schematic itself is the "correct" one for my 2023 axis.

can anyone share a pic on how their wiring is??
 
S2 represents 9:00 on the trombetta; S4 represents 3:00 on the trombetta

according to the thor diagrams, the ground, white, should be at S4, and the yellow/black (goes to the intellic) at S2. I did switch these a few mins ago. same result.

also, I shook the wires with that 5 amp fuse
I might try tracing that wire a bit
 
UPDATE! I figured it out. took a closer look at the schematic for the trombetta. turns out that the PO or a shop had put the yellow and red small wires on the wrong Post. moved it from the chassis battery post to the house battery post. 3 days now and the BMPro is reading both the house and chassis batteries on a nice float charge of 13.5.
Once again a happy camper

Glad you figured it out! A classic example for learning how basic things in your RV work... AND doing basic work yourself if physically able. Saves a LOT of frustrating troubleshooting when you know it's done correctly from the start! 🙂 That said... tough to babysit the factory kids building them! 😄
 
And thank you for coming back and sharing the solution with us. This might help some future Rv'er with a similar problem.
