Strange electrical problem

[eektech909]

I have a '95 explorer. My battery seems to lose juice when I have my headlights on but only when I'm stopped. When i'm driving, it seems fine but when I stop at a light I can see the battery meter start to slowly decrease. The alternator was replaced in February. Could it be a bad alternator? I had 1 brake light out that I replaced. Any ideas?

Can you hook up a digital multimeter to the 12 volt and monitor it? The fact your battery meter starts to slowly decrease tells me the system is not charging correctly? I'd recommend doing a load test on the alternator & battery. It could very easily be a bad alternator, voltage regulator, etc.. Try to monitor the voltage with the key in the off position and when running. When running it should be above 12 volts.

Check and clean your battery connections.
