Signs of a failing diode can be a poorly charging battery, or, if you detect "noise" in the electrical system. This can be caused due to a failing diode leaking AC current into the system, which can confuse electronic modules that are only expecting direct current. A shorted diode could allow excessive drain, or "phantom draw" symptoms.
