More OVP Questions.

This OVP is the cause of many problems. What causes it to malfunction or go bad? Burned contacts? Voltage spikes? Age?

ALL of the above cause problems! ON some models from 1993 thru 1995 the relay itself was defective due to poor quality control at the factory, cheap diode & BAD solder connection.
