What should the dash gauge be right after start?
What should the dash gauge be right after start?
Right after start, at the alt or batteries (doesn’t mater) it will be low – the batteries are charging. Wait 5 min then measure. It should be 13.8 volts. If its 12 its too low. Alt neefs replaced. The dash gauge in these trucks is a joke. Huh, my answer when reading the post title was gonna be,,,, Stock gauges suck!
Why does my voltage guage only show 9-10 volts?
My voltage guage usually points near the red mark at 9-10 volts. Batteries cranks the starter quickly and it does not seem to lack any electric power. Some times driving, it will raise to about 12 V, but never above, and the next minut point at 9 again.
What should the voltage be on a truck?
You want 12.4v -13v at the battery with 12.8v being ideal with the engine off. x3, load test the batteries one at a time first. Is the tach behaving nicely? or erratic?

How does the battery gauge work on a car?
Display of engine temperature in Degrees C input from cylinder head temperature sensor. Displays the code (0-255) for the battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.
What does the tachometer show on the fuel gauge?
Tachometer will indicate present RPM. Display will show 0 if input is no received, if input received is invalid for one second or more, or if engine RPM is 0. Displays the code (0-255) for the fuel sender input to the HEC. The fuel gauge will display a filtered fuel level value.
