Other than the upper 15A peak output potential, the alternator is physically distinctive with the 55A Variation:

could be the rotational pace in revolutions per minute (RPM). Pretty old descriptions of alternating present-day devices in some cases give the frequency when it comes to alternations for each minute, counting Every 50 percent-cycle as just one alternation; so 12,000 alternations for each moment corresponds to 100 Hz.

If your noise is absent then you'll want to Test the other elements upstream of your amp. Very first, connect the head unit RCA cables on to the amplifier (assuming you have got crossovers or equalizers amongst the two). Commence the motor.
