hey buddy ! hope all is well. So i did a couple of test. So when the maf was connected, it was getting readings that didnt check out. And when i disconnected it, it all had the right voltage, But in the grounds were reading 0.03

Question my 1st wire is 8.3v instead of 5v. 2nd wires is 12v. 3rd is gnd 4th is 8v instead of 3.5v . 5th is gnd. Why do I have 8v instead of 5v and 3.5v
