[CA] [CA11] RS125 - No communication

[Zulu]

The GPS receiver was working fine but i noticed it started taking longer to get a fix until it stopped working. The GPS status screen on the Raymarine E120 MFD displays no data.
I changed the battery in the RS125 unit but still no data.
I then found the thread "RS125 - NO FIX being reported on Pathfinder Series Display or Multifunction Display" on this forum and measured the voltage between the different pins as prescribed.

The results are as follows:
----- Between pin 1 (red) and 2 (black or shield): +11.9VDC
----- Between pin 1 (red) and 3 (yellow): fluctuates between 0 and 3.8 VDC
----- Between pin 5 (green) and 2 (black or shield): +11.9VDC
----- Between pin 4 (brown) and 2 (black or shield): No voltage

The white cable in the attached photo is the one coming from the RS125. Pins 4 and 2 are connected together so that explains the 0 voltage. It seems like the problem is between pins 1 and 3. Is there a common cause for this?
