Just want to know what voltage is considered to high. I know fluctuations are normal but over the last couple weeks mine on the factory volt meter is above 14. So i installed a digital voltmeter and it is reading 15.5v at idle and up to speed. That seems too high. I also get a warning chime randomly but no info on the DIC and no other warning lights. Don't know if they are related. It is an aftermarket NAPA reman alternator which has been installed for almost 2yrs. I believe the stock one was 105amp and this one is suppose to be the same. Should I replace it or is there no need for concern. Don't want an electrical fire. Occasionally it would run that high but then settle down just a bit over 14 and sometimes under.
