Voltage issue

Hey everyone, IDK if there is another thread like this one but I have an issue with my 5th gen. when I start the car the volts goes from between 12.3 to 14.4 warming up then 13.9 fan running, then I decide to turn on the headlights (HIDs) and the OEM installed Fog lights (HIDs too) the volts drops to 13.5, BUT if I turn the A/C on everything drops to 12.5v; so I rev the engine to 2K-2.5K and it goes up to 13.8v but when I let the RPMs goes to idle it drops back to 12.5v and the car's RPM drops to 200-300RPM before going back to normal, so it doesn't matter what combo I do, is the same numbers. Now, do I need an Alternator? a Battery? maybe ground wires? any ideas? thank you

Re: Voltage issue

the alternator isn't always engaged so the voltage will fluctuate. unless you're having issues with the alternator not putting out enough to keep everything running then it's fine.

Re: Voltage issue

Seems about right to me. Different loads will read with a slight variation depending on how tight the voltage regulation is along with current capacity of the alternator. Applications with additional high power accessories may experience problems if the system draws excessive current. Be sure to run the proper sized fused conductors and good grounds for any additions to your ride.

Batteries lose their ability to retain a charge as they age until one day, click,click,click.
If it's over 3 years old and giving you problems, replace it!

Re: Voltage issue

that is normal. It will always fluctuate due to different loads on the electrical system. That is what your alternator is for, to maintain constant voltage to the battery and keep it charged. Now if you see your battery begins to stay under 11 volts consistently after use, you may have to change your battery, that's when you should worry.
