So I had a super silent sounding system in my vert with my M20 engine. I swapped in an S52, changed nothing on the stereo and now I have alternator whine or at least a low whine in the system. Sounds like alternator but it doesn't seem to change with the engine speed.
I am using the same e30 engine ground wire and grounding point I did previously to the new engine. Could this be an issue with the new alternator? Everything functions perfectly electronically speaking, grounds check out good, voltage is good, etc. Do I need to add an additional ground to the engine block maybe?
