Abstract
A diagnostic tool for testing the performance of a component of a vehicle includes a processor configured to process test information from an alternator component of the vehicle and control and activate the alternator component. The diagnostic tool further includes a memory configured to store the test information of the alternator component and software that operates the alternator component of the vehicle, and a sensor configured to sense the output voltage of the alternator and ensure that the diagnostic tool is properly operating the alternator component.
Claims20
A diagnostic tool for testing the performance of a component of a vehicle, comprising:
- a processor that processes test information from an alternator component of the vehicle and controls and activates the alternator component during an alternator test;
- a memory that stores the test information of the alternator component and software that operates the alternator component of the vehicle;
- a motor having a pulley that is connected to the alternator;
- a first load component controlled by the processor to put a first load on the alternator during testing;
- and
- an analog to digital converter (ADC) that provides an output voltage of the alternator, wherein the processor determines a ripple frequency from the output voltage.
A method of testing an alternator, comprising the steps of:
- starting an alternator drive motor with a processor of an alternator tester;
- receiving a voltage output from an analog to digital converter with the processor;
- determining a first ripple frequency from the voltage output with the processor;
- determining a second ripple frequency after a first load is applied by a first load component that is controlled by the processor;
- calculating a first difference between the first and second ripple frequencies by the processor;
- and
- determining if the first difference exceeds a predetermined percentage by the processor.
A diagnostic tool for testing the performance of a component of a vehicle, comprising:
- a processor that processes test information from an alternator component of the vehicle and controls and activates the alternator component during an alternator test;
- a memory that stores the test information of the alternator component and software that operates the alternator component of the vehicle;
- a motor that drives the alternator during the test;
- a power supply that supplies power to the motor during testing;
- a first load component controlled by the processor, wherein the first load applies a first load on the alternator during testing;
- and
- an analog to digital converter (ADC) that provides an output voltage of the alternator, wherein the processor determines a ripple frequency from the output voltage.
