Hi, everyone I was testing out each cylinder and the power balance test. I was testing the motor for compression power and all cylinders passed the test thank god. I am here with a question and the part where the test said NG when it came to the psi test and the cylinders #3,#5,#6. I got some numbers in high 135psi and some maybe it was the voltage out put numbers with the negitive number. The compression is not what I am really worried about but it's the voltage in the voltage harness. Is there anyone with the exact idea how this test was supposed to really happend.
