Tested my new HO alternator. Meter says 16V 1 battery installed on car.

crank pulley? is that the larger pulley above the alternator pulley that is attached to the SAME belt as the alternator?

u'll kill all ur equipment man //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif 14.4 is maximal safe voltage otherwise 13.8 is ideal

I may not be an electrical engineer but I call BS. My mothers car idle's at 15.1-5v with the stock alt and every things fine, and when my voltage regulator went out in my car I was still driving it with 19v idle and all that happened was my lights got brighter.. but then again I don't have an ECU in my car so maybe 19v would kill another but not mine //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
