[QUOTE="kevinatfms, post: 16331168, member: 39344"] It should read 14.5v+ with a large load over a 30min drive. Batteries usually only have a 90min reserve and that is without a ton of electrical load. Sounds like the alternator is not charging at full capacity. Maybe a damaged regulator from the sound of it. If you wanted to confirm you could check the resistance of the regulator control circuit. That would tell you 100% if the regulator field is damaged. Unplug the black 3 pin connector on the back of the alternator(with the vehicle off). Check for an ohm reading between the one of the outer two terminals and the alternator case. If one of the terminals when grounded shows 1.2k-1.6k ohms it would indicate a good regulator field and that its a PCM charging control circuit issue(a bad PCM). If the ohm rating comes up high between 20k+ohms there is an issue with the regulator field and the alternator needs to be replaced. [/QUOTE]
