Some Electrical Troubleshooting Notes for Metal Plating
Checking for AC Ripple from Rectifier. If the rectifier has recently dropped a diode or has degraded filter capacitors, it may not be filtering out the unwanted AC current properly. When this happens, the AC ripple is increased and can cause plating problems. Usually 10% is a generally tolerable amount for most applications.
