Forum;

I believe this component (shown below, broken) was a diode intended to suppress the inductive spark generated when the Park switch contact opens. This would minimize contact erosion and also radio frequency noise, but this component is not present on all Wiper motor assemblies...could it be it was only fitted to Wiper Motors on cars with radios?

Can anyone shed some light or tell me if I have this right...also confirm the polarity (I believe it should be Cathode to 53), which is obviously not possible to determine when much of the component is missing.


TIA
