However, during the checks, I noticed the alternator voltage looked too high. It was 16 volts. I wonder what the affect of that would be. He said the alternator was an aftermarket replacement and the battery had been replaced.
I suggested he have the battery tested. I wonder if the battery was failing, could its impedance rise and the charging rise commensurately?
