I have a MacBook air with unstable ppbus. In the tester I have 5v after a few seconds it goes down to 3 then to 0v and so on constantly. The t2 chip and the controls get hot. Ppbus has 12v as if the charging IC is fine but after a few seconds it drops the voltage and goes up again. Do not have p5vg3s
