Alternator testing at advance auto

[timarr]

I spent some time today to test my 5 spare alternators . Went to advance to use their test bench. The code you need is p7157 which is the code for a 80s 100amp si27 alternator. use electrical connector c. hook up 2 wire c connector in its spot, positive to positive post and ground wire not to case but negative post. then run test. after test you can view its results . I had good results on all 5 ,good luck with yours!

I would make sure that the isolated ground in them is still isolated

How do you check the isolated ground?

 

[dependable]

Make sure there is no continuity between ground stud and alternator casing with ohm meter.

Yeah, set a multimeter on resistance, and put it in the ground terminal and the other lead on the case. It should read infinite if it's still properly isolated.

the reason for my post was to take a know cucv si27 isolated ground alternator to advance and use their test bench and how to hookup to check output .
