Recently replaced the original battery after it refused to charge. After replacing it with a brand new battery I have been noticing the battery gauge drop from 14v to roughly 12.5 after driving and running the truck for around 30 minutes. Truck is all stock except for battery at 32k miles. Nothing has been messed with except the replacement battery. Is this common to see that voltage drop on the gauge and just didn’t notice until I have been more cautious since the dead battery or is there some things I should look into?
I checked continuity to all the terminals connected to the positive side and everything is passing enough to beep the multimeter. Is there a possible fuse problem (if so do you know where it is?) among a possibly bad alternator? If you have any information it would be much appreciated. Thanks, Lance.
