So, mechanic here. Some (most?) trucks have a battery volt meter in the instrument cluster that reads the voltage at the battery (for simplicitys sake). Cars, not so much, but as stated theres a battery light in the cluster. Toyotas light up the abs and vsc light (if I’m not mistaken) when the alternator goes out and the car is running on battery power alone.
