Battery over charge

[Glouie18]

Good afternoon everyone, I have 2005 ford explorer xlt 4.0L I'm looked at other thread discussing this electric issue and tried almost everything but no luck. I have change the terminals, batter new alternator new, cleaned all grounds, check all fuses and went around with the multi meter to see if there any voltage lose or something not getting not getting current no luck. When I turn on the car everything works fine no check engine and no other warning signs, but as soon as I but it in drive and accurate the battery guage goes up and turn off all internal electronics but the engine. Anyone have any idea what can be causing this problem?

What happens if the headlights are on?

If the battery is over charging it can only be the alternator.

They turned on perfectly fine, but I just found out the last owner didn't install the touch screen radio correctly cause a short. I did notice that he had the wires hook up to the dimmer switch idk if that can cause a problem.
And thank you for the help I will look into that next

Did you ever figure out the issue I have an 04 Eddie Bauer doing the exact same thing

How can it be the exact same thing when the description of what is happening is vague at best?

All I can make out of that opening post was turn off all electronics but engine, which "all" isn't nearly specific enough, since the engine itself needs electronics too. I can only guess that what was meant was the gauge cluster stops working, possibly radio as well?

The general procedure after considering what is described below, is pick a subsystem that isn't working. If there is a trouble light lit on the dash, use a code reader to pull codes. If a standard OBD2 reading finds nothing, use a code reader capable of Ford-specific codes that are outside the OBD2 code set. If no codes are present, trace the circuit for the subsystem that isn't working, to see where power stops, trace it along its route to the battery, especially checking the fuses, relays, condition of the wires and connector contacts, including that it has a good ground. It may help tremendously to get a hold on wiring diagrams applicable to your model year.

Battery overcharge results in boiling off the electrolyte. It can happen from a bad battery, or excessive voltage, or slowly from high ambient temperature.

If it happens from excessive voltage, you can measure the voltage and determine that. If the voltage is excessive (over about 14.6V while connected to (an otherwise properly working) battery, then the alternator regulator has failed.

I struggled to make sense of the 1st post myself..
We need more specifics..

you could have a shorted wire in transmission causing regulator to go to full charge when you put it in gear...check the transmission connections
