C3 Part_4 clone strange board modification
#1

Greeting to All Members Cheer2
Last week a friend from neighbouring garage brought his C3 mux which stopped working. We opened the mux and noticed the modification on the board 533 . Please see the photo. What the hell is that ? Any idea what is the purpose of this mod. I am using SDconnect and have no experience with cloned C3. His C3 does not connect to a car although it is correctly recognized by the laptop via serial port. Can anyone advice on the matter , please.

At 1st, I wondered if it was a poor circuit board & they've used a wire link, but the tracks don't seem to suggest that.
You could make a note of the links with some tippex / marker & remove & see if the MUX works.

Not sure what's on the other side of the PCB, unless it's some workaround ?

maybe it was a faulty init send back to china and the "engeneer" "repaired" it and just rebox and resel it as new , this is fore sure on the relay board , maybe if u remove the bridges and fit 2 relays it might maybe and after u love it long time it might work
i also have one of this "i hope it will not die again on me" c3 units it could have damage tracks on the other side , i have opend and modded mine a couple of times and there are tracks on the both sides
