i just replaced my alternator on my 2002 4.0 cause i thought it wasnt working properly, i put the new one on and the same thing. Both alternators tested pass. I ran another cable from the alternator to the battery to eliminate the orginal wire if that can be the problem and still no 14 volts when running. Also ran another cable from alternator housing to fram to ensure a good ground and still nothing, im lost... any ideas???
