Good evening, and thank you for your attention. We currently have a forklift with the active code 3501.1, and according to the description in the message/error table, the AC-3 Power Control interface card needs to be replaced.
We have removed and inspected the controller's PCBs, so far finding two damaged components: two integrated circuits and a blown 10-amp fuse (position 7F3).
We have identified one of the integrated circuits as the ADUM1286 (Dual-Channel Digital Isolator). The other one is unrecognizable due to being burned; we can only determine that it is from the brand LT (Linear Technology). Both are connected through pins 6 and 7 of each IC, respectively.
We were informed that the issue originated after external lights were connected to the controller's output (+UB) in order to have control over the lighting after turning the forklift's ignition key.
Since I cannot share an image or indicate the position of the integrated circuit because it is not labeled on the PCB, it is located on the second board near the +UB and +UB(B) input.
I appreciate the help provided in advance.

I read your post and I am working in a similar unit like the one you have. According to your description the circuit you are looking for is the LT4356CMS-3#PBF , PART MARKING ; LTFFK 10-Lead Plastic MSOP.
Merhaba Parça numarasindan kontrol ettim bu elektronikler üzerine fazla akim çeken parçalar baglandiginda maalesef sorun çikartiyor. Bu nedenle kontaktör çikisindan akim almanizi tavsiye ederim.

Hello, I checked the part number, unfortunately these electronics cause problems when parts that draw too much current are connected to them. For this reason, I recommend that you get current from the contactor output.
