Hi I have a m62 eaton blower with the electromagnetic clutch. In the past couple months ive noticed the psi have droped from 10 down to 7, and my dyno plots Here have small sketches in them. I was wondering if maybee my magneticluch is going bad ? I hear there is a way to diagnose if it is going bad by looking at some aspect of it, would you guys know anything about this ?

Thank you
