Default Sluggish Voltmeter

Immediately after starting the car, I normally look at the oil pressure gauge. But for some reason, today I watched the voltmeter. After starting, it immediately jumped to ~10 volts, and then took another ten seconds or so to rise to ~14 volts. Is this normal, or do I have a problem? :confused:

You have a couple of variables here. How fast the alternator's voltage regulator reacts and what the sampling rate of the voltmeter is. I wouldn't worry about if you DIC isn't returning to the odometer when you start. That's , usually, the first sign of a low battery/weak charging system.

The gages are slow to react, try watching the voltage on the DIC instead of the analog gage.
