Broken left most pin in UTP connector on PCB board on 500A shunt, voltage reading 0.00

My BMV-700 shows battery voltage as 0.00, even though it is 12+ volts. It does however show Amps in/out. I found that the left most pin on the PCB board on the 500A/50mv shunt is corroded and has no "spring" left in it to make contact with the UTP communication cable.

Can someone tell me if the left most pin on the UTP connector is used? If not, what else could the problem be?

If I do need the left most pin to work, where can I go to get a new PCB board?

See pictures below. Thank you.

Hi @omglasercats, yes, all pins are used - please contact the authorized dealer from whom you purchased the unit to inquire about a replacement PCB; in most circumstances this will be a simple warranty replacement procedure, but each dealer's exact process may vary somewhat.

If you're not certain where you purchased the device, you can fill out this form using the device serial number (located on the original box or, if you no longer have it, also located on the sticker on the back of the display head) and Victron will reach out to the dealer for you.

Excellent, thank you. I do not have the box, the installer never got it to me.

I found this quick install guide, but I still cannot manage to get the unit out of its mounting bracket. I am afraid I will break it. Any tips?

Wy dont you just change to socket? Can you send me a picture of both sides of the PCB? the socket seems to be a standard RJ45 available at any electronic shop. Send me the pictures of the back side. I will appreciate.
