Alternator readings flagged on tester
Hey,
So recently I tested my alternator at Halfords and they used a GS Yuasa battery tester which also tests alternators.
It tests the battery in 3 stages - loaded (lower voltage), unloaded (upper voltage) and diode ripple.
My 2001 S60 failed in the loaded stage with AC, rear defrosters and high beams on (1.5k to 2k revs). The GS Yuasa battery tester flags an issue when the max voltage in the loaded test is less than 13.8V. Mine was 13.42V. Could I get an idea of what could cause this issue? I know the alternator is one, I was wondering if there are any other components that could?
I have attached an image of the test.
