Two alternators what kind of vehicle is that on?
Different question with all the different gauge setup is there a certain reading like digital or analog instructions as where everything should be as in normal. reason I'm a novice at guessing where things should besides the stock gauges that are funky some times.
Cutaway vans used for ambulances and buses often had two alternators. Mine was a bus and also had two ACs.
As for what is normal. The factories deliberately don't give specific data in their instruments. The oil pressure gauge in my PSD has a needle that goes up when the engine starts, so it appears to be analog. But the sensor is just a switch and there is a resister in the dashboard that sets the needle at "normal". I am working on making it a real meter.
Do a search on each meter for your vehicle and you will find more info than you want.
