Do I need to turn on all accessories when I do this test? I marked with the radio and headlights on high beam and was at .045vac I wonder what the ac compressor draws. I'm thinking this alternator is bad, because with the headlights off it was at .032 Ideally it's supposed to be below 50mv. which is .050
