I was recalibrating the TPS so I had the ignition on but the engine not running. I was hearing a hum from the passenger side of the engine. By using a piece of hose to my ear I tracked the hum to the alternator. What would make the alternator hum with just the ignition on ? I do not recall hearing this hum while adjusting the TPS in the past.
Thanks
