Battery ok, fuse ok, 230V supply ok, but not work on battery

Evening,
I have a boiloid premium with a CM-510 controller,
I cannot use the cm-510 on battery only mode,
so I did many checks :
- fuse F1 ok,
- CM-150 on AC/DC supply ok,
- battery on another CM-530 ok,

last chance checks :
- I opened the CM-510 and checked if any component or link is burnt, nothing
- no bad smell
- the fuse seems to be only for the battery

as the AC/DC supply run the CM-510, I am sure after the fuse everything is ok

I have 3 test points or link before the fuse, it looks the board have multi layers, maybe a short one of this layer, but I think it may be stupid to fit weak component before the fuse, and I may notice problems directly on the battery in this case.

any idea, like a battery failure reset procedure or something I missed?

else this controller will loss a lot autonomy by being cable to supply...

Thank you for any help

Regards,
Florent

My first thought is that the input jack socket on the CM510 is damaged.
I can't remember the exact schematic, but I think the switch function of the socket is used to connect the battery when the plug is removed. If this is damaged, then the battery will not connect.

Many thanks,
that is it,
when ac/dc supply is unplug the battery negative is link to 3rd pin of the socket direct to capacitor C3.

when I link it, it is working on battery.

Now the challenge is to repair this socket or replace it.

sure the solution is not academic, but the screwdriver in the socket to move the negative pin worked perfectly... :roll:
