I have a 2003 Jeep Wrangler- 6cyl- w-a/t & a/c. While driving home the check gauges light came on- the code p1682- charging system voltage too low. The Jeep seems to be running fine & the battery gauge is just under 14 amps
Help & thanks in advance

Could be a problem with the computer controlled of the alternator's field generation circuit-
