Hi there again , I tried the voltage on the fuse and no voltage at all . I have not put the analyzer yet waiting for the check engine to light up. Last time I used it gave mi no codes at all. Does the fuse suppose to have voltage once I turn it on I think it should. And I did check fluid and flowter. I’m 60 years old and I have a good background with mechanics I built my first car from ground up at 16 years of age. But I am somewhat lost with so much electronics on newer cars. Thanks for help ahead.
