2008 Quest Base 3.5 electrical problem with vids

[martman100]

Van has new battery as the other suddenly went dead. Radio has not worked or worked intermittently for a long time. We thought it was the radio itself. After replacing the battery the radio worked but then stopped again.

The other day we went to start it and it acted as if the battery was really low when cranking but it did start and then the radio worked again. However, the gauge cluster showed some problems. The needles were all buried and shaking and it seemed that most lights on the dash came on until it started.

I am thinking this is an alternator problem since I believe these also have the voltage regulator in them.

Last night I went out to roll the windows up and it was like the battery did not have enough juice to roll them up. Went to start it and had same problem as before with slow cranking and gauge cluster. Windows did roll up when started.

Here are two videos from this morning with the behavior. Would appreciate any help in what could be wrong. I am a pretty handy with cars and do most if not all of my repairs when I have time. I don't just start throwing parts at them though so maybe someone has suggestions.

One thing to note I put a volt meter on it while running and it was showing between 14 and as I turned everything on it did drop to 12.99 once or twice.

Thanks in advance.

I can't post urls so do a search on Youtube for 2008 Nissan quest electrical issue. I posted these today so hopefully they come up with that search.

Should be two videos

Video 1 (first start today)
Video 2 (right after the video above. My wife was doing these so she basically turned it off and then went to restart again)

This does seem like an alternator related issue. Reading voltage across the battery with the engine idling should always be ~14VDC. Lower is going to cause weird issues like you describe.

My previous Nissan had alternator issues when it was 12 yo with 200k miles. 2008 is only 9 yo but with higher mileage (how many miles on it?) it could be going out already.
