How do I perform a battery and alternator check using the Innova 5210?
From the Main Menu, select Battery/Alternator Test and choose either Battery Test or Alternator Monitor. For the battery test, turn the engine off, turn the ignition on without starting the engine, turn on the headlights, and follow the on-screen prompts including three engine start/stop cycles. Results are displayed with LED indicators: Green = Good, Yellow = Normal, Red = Warning/Bad. (Pages 26-27)
