Default voltage dropping with rpm
Took my car on its first night time drive of the summer and the voltmeter stays at around 12.8 when driving down the road, but the voltage creeps down to about 10.5 and 11 while I am at a stop light. Then, it recovers as I go through the gears. This is the first time it has acted like this. My idle rpm is about 750. The battery is 2 years old.

Any advice on what to suspect?
