Help Needed Dead Battery

[jason741]

I have a 2004 F350 with a 6.0 I am having a battery problem. My battery light comes on, so I had the alternator checked. It checked good. I had it checked at 3 different places and all said good. I installed back on vehicle and installed 2 new batteries. Everything worked good for a few hours and my light came back on. Now my battery is dead again. Truck off 12 volts. Truck running 12 volts. Tested vehicle running and alternator puts out the same voltage that the batteries have. First it started at 13 volts now I let it run with lights on and it went to 12. Any ideas? Could the alternator be going bad? Ant certain fusable link? Any help would be greatly appreciated.


Thank You!

yea sounds to me like it might be going bad. 12 volts with it on is low. i would expect to see a number like that if you were idleing with a/c on full blast lights on wipers on etc..

You need about 14.2 at idle to stay ahead of everything. Cables o.k.? Volts making the trip?

(pictures or what im talkin about comin in a few minutes) the problem im havin now that i replace the water pump.... is my battery light coming on, its a pain in the ass, 2 new batterys, that went dead. i tested alternator and autozone, and it passd with flyin colors lol. anyways, the plug on the alternator there was one wire that was cut or burnd, couldnt really tell. i cutt the whole thing off, and well youll see in my pick ill put up.

the battery cables are crappy, so im replacin those this friday,. hopefully its just the cables and the 3 wires from the plug that are lettin my battery get draind or not readin the voltage right, ill keep everyone posted,
