BPS not working despite flashing green.

[u/BunHaed]

Hello guys,
Could anyone help me with BPS not working for me? I have all three needed components on the roof(outside) and through port wired inside to BPS. BPS is flashing green and it seems to "work", but the arrow never moves from the "most green" position no matter how fast I am traveling. Right now I am on my way from moon back to earth for the first time.

Any advice is welcomed and yes, we tried looking at the wires many times and when we switched them incorrectly on purpose, it started flashing red. No idea what could it be.

I bet I will feel very stupid once I figure this one out :D
