After a trip, my battery was hot and acid boiling. I have new alternator but dont know if something else can cause an overcharge of some kind. Back in the old days it used to be a regulator but I know if there is something like that today. Brief history on alternator and batteries: I purchased reman alternator and after about 6 months found that the reman alternator was my amp draw short. They Oriellys gave me another reman and same problem. Then they gave me a brand new alternator and bingo, no amp draw. I dont know if the short caused my batteries to lose life and with the new alt, my batteries went south? I feel like my batteries were overcharged in some way or current condition of batteries (being less than new) caused normal charge to cook them.
they have a voltage regulator in the alternator. i had one go out and cooked some stock batteries. it was making like 15 volts. i replaced the batteries (3 years old) and then put in optimas and it fried them too. finally found the overcharge and had the alt rebuilt w/new regulator and no more problems.

If you have a volt meter, check the output at the back of the alternator and see what you got.

Had Oriellys check the alternator. The reading was 14 volts output. They said that was okay. I now have 2 new batteries. I have to admit Oriellys has been good about giving me replacements. They stand behind there warranty.
one of these CYBERDYNE <plug-in> Voltmeters would help you keep
a watch on your electrical system.
w/ the truck OFF itll read the battery voltage...
w/ the truck RUNNING itll read the alternator output or
about 30 bucks available in several different LED colors
(RED IS REALLY REALLY BRIGHT) in both a plug in and a
MOUNT style. VOLTMETER OPTION LINK
fwiw i dont use mine all the time...plug it in when im
curious or on a long trip (i keep it in the door pocket)
and you can pull the unit outta the socket ever so slightly
so that its still IN the socket but not necessarily "ON"

Where did you buy yours from? It costs $63 from Summit Racing. I like the idea, seems like a very neat product.

You can purchase a similar plugin product with an LCD display at Autozone for less than $20. I do not use mine much since installing the Brakesmart brake controller as the display shows the system voltage.

With your alternator and Battery problems did you ever notice any clicking sounds from behind the dash? Behind the radio and A/C control area.
I have been trying to figure this one out for over a year now.
04/F-350 6.0 torque shift 4x4 Four door long bed
My alternator went a couple weeks ago. I saw all kinds of crazy stuff as a result: the ABS was malfunctioning (braking more on one side than the other), the overdrive off light on the shifter would flash sometimes and clear when shut off and restarted and the speedometer was all over the place from 0-30 mph. Once I hit 30 mph the speedo would straighten up until I turned it off and restarted. I would only hear the clicking in the dash when the batteries were low. I wound up replacing the alternator and both batteries - batteries had bad cell (dropped to 8v on 3rd cell under load). Everything is back to normal now.
