Review on ACDelco 335 1036 Professional Alternator by Mark Patterson

GM technology after disappointing results with a rebuilt branded unit. I ordered this new Delco made in Mexico, unfortunately this unit makes a squeaky noise under load and low power. I will update this review once a replacement arrives. The second device made the same high-pitched squeak under load, but had output voltage fluctuations and charged easily. Voltage and current did not correspond to the nominal power. The maximum output current was 40 amps. Return the second block.
