  • 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.
