System and method for testing alternator default mode operation
First Claim
1. A method for testing a default mode of an alternator, the method comprising:
- detecting, with a processor of a tester, an absence of a communication signal at an alternator coupled to the tester, said communication signal being simulated by the tester to include at least one parameter associated with a vehicle;
testing, with the processor, upon said detecting, whether or not the alternator enters a default mode of operation, the default mode being indicated by a preset output voltage uniquely associated with the default mode and monitored by the processor; and
indicating, with the processor, whether the alternator failed or passed said testing.

Abstract
A tester for a default mode of operation of an alternator is provided. The tester includes an internal memory having computer executable instructions and a processor coupled to the internal memory and to an alternator via a communication bus. The processor is configured to execute the computer executable instructions in the internal memory to provide at least one parameter associated with a vehicle to the alternator simulated as a communication signal over the communication bus, detect an absence of the communication signal at the alternator, test, upon detecting the absence of the communication signal, whether or not the alternator enters a default mode of operation, the default mode being indicated by a preset output voltage uniquely associated with the default mode and monitored by the processor, and indicate whether the alternator entered the default mode successfully.

10. A tester for a default mode of operation of an alternator, the tester comprising:
-
an internal memory having computer executable instructions; and a processor coupled to the internal memory and to an alternator via a communication bus, the processor configured to execute the computer executable instructions in the internal memory to; provide at least one parameter associated with a vehicle to the alternator simulated as a communication signal over the communication bus; detect an absence of the communication signal at the alternator; test, upon said absence, whether or not the alternator enters a default mode of operation, the default mode being indicated by a preset output voltage uniquely associated with the default mode and monitored by the processor; and indicate whether the alternator entered the default mode successfully. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer readable medium of a tester for an alternator, the non-transitory computer readable medium including computer executable instructions thereupon, which when executed by a processor of the tester cause the processor to:
-
provide at least one parameter associated with a vehicle to the alternator simulated in a communication signal over a communication link; detect an absence of the communication signal at the alternator; test, upon said absence, whether or not the alternator enters a default mode of operation, the default mode being indicated by a preset output voltage uniquely associated with the default mode and monitored by the processor; and indicate whether the alternator entered the default mode successfully.
