What should the voltage be on a Toyota alternator?
The battery provides the initial voltage and amperage to crank over the engine, afterwards the alternator takes over in generating the power needed to run the electrical systems in the vehicle. At idle under minimal load, a Toyota or Lexus’s voltage at the battery should hover at or above 14 volts (many times closer to 14.5).
