I'm getting a high pitch whine around the 2-3K rpm. It is independent of the drive train and seems to be related directly to the motor. If I put in neutral and rev up to that range, I can hear the whine. Pitch doesn't really change but volume increases. It sounds very similar to a supercharger haha
Interestingly enough, this correlates with the fan running, both with AC on and off. It also correlates with if I have the speakers on and how high the treble is turned on. For additional info, I play music through my system using a FM bluetooth player connected to the cigarette socket on the dash. If I turn it up too high, I do hear some static but this is a steady high pitch whine.
Sounds like EMI or am I chasing the wrong thing? Or is there something that engages the fan and maybe above a certain RPM it starts whining
