What Causes Alternator Voltage To Fluctuate at Susan Jensen blog

What Causes Alternator Voltage To Fluctuate. Leaking or shorted diodes can often cause a visible fluctuation in the output voltage of the charging system. If the lights stay a constand brightness while the voltage. If the alternator’s voltage regulator (which might be built into the alternator or external, depending on the vehicle) is faulty, it can cause voltage fluctuations. If varying the rpms causes the voltage to fluctuate between 13 and 14.5 volts, your alternator is in good shape; This is often a yellow light, shaped like a. This was what caused the. The alternator is faulty as the output (measured at the alternator on an oscilloscope after the regulator) fluctuates. Engaging the a/c provided additional load on the crank pulley that was enough to cause it the outer ring to stop rotating. If, on the other hand, the voltage remains the same or. Turn on your headlights while it is doing this weird voltage jiggling. Perhaps the most obvious indicator of an alternator issue is a dashboard warning light. You can test the regulator using specialized equipment or, replace it as a Bad diodes can also allow current to leak from the battery back through the alternator to ground, causing the battery to run down overnight.
