Can someone offer advice on high voltage? I have a 740 (1990) that has a code pointing me to high or low voltage. I discovered this while trying to clear out a code for another issue. I checked the voltage at the battery with the engine running at idle and it was 14.4v. I believe that is high but not by much. Tried switching the regulator/brush pack (it was the original one that I put back in) and it brought the voltage to 14.3v with the engine running at idle.
I believe the battery is good as I measured 12.4v after it "rested" for a couple of hours.
Anyone care to comment on this? I am wondering about the diode bridge. I don't know what to expect if I have a bad diode in the diode pack. I tried to measure ac voltage and did not get much voltage at all, well under a volt.
thanks for the help
