colerongo Posted June 30, 2011 Share Posted June 30, 2011 You might want to start by cleaning all connections with electrical parts cleaner and applying dielectric grease to them. Also cleaning the AFM with MAF cleaner would be a good idea. Go through your grounds and make sure they are all clean and have dielectric grease on them. This is the best place to start, from my experience. Make sure all connections are snug and there are no cracked/broken wires while you do this.
