DSkey Posted July 23 Share Posted July 23 I have a remote controlled relay which triggers a 12v solenoid running a yacht windlass (12v 1000W) The contacts on the small relay in the remote unit keeps burning out / welding shut. I assume this is back emf from the big solenoid sparking across the small relay contacts. I think I need a snubber capacitor across the small relay contacts - But I have no idea what to use?? Any advice welcome - thanks Quote Link to comment Share on other sites More sharing options...

Adrian Girling Posted July 23 Share Posted July 23 Maybe try posting on allaboutcircuits.com. There are a host of experts who are very helpful. You will be asked to provide details of the components and probably a schematic. It could just be that you need to put a diode in parallel with the relay and/or the solenoid to short circuit the large reverse voltage when the current stops flowing Quote Link to comment Share on other sites More sharing options...
mpbarrett Posted July 24 Share Posted July 24 needs a reverse diode across the solenoid. mike Quote Link to comment Share on other sites More sharing options...
