Video of the 14v gauge on cold start with the intake heater running. If you set the high idle it draws more power as more air is pulled across the heating element. Voltage goes back to 14v when the grid heater turns off.
Having no frame of reference for normality I figured I would get opinions on this behavior.
2008 A1R with 260a alt. Seems like the more powerful alt should be able to maintain closer to 14v than what I'm seeing but again I have no frame of reference. I just can't imagine how low the voltage must get on the 100a alternator trucks.....
