After I start my truck, the check guages light stays on for about 5-10 seconds. I don't remeber it staying on that long. Is there something wrong?

 

Is there a gauge that is not reading until just before the light goes out?
On mine, when the voltage is being pulled down due to the grid heater, or when the oil pressure hasn't come up yet due to sitting for a couple of days, my check gauges light stays on until they come up to a normal value.

I'll check it out. Thanks
