Replacement rectifier, OMC part number 586271, matches part number of old part, but wiring is different. Old part has purple wire, new part does not. My understanding is the purple wire is for accessories and should be getting voltage from battery. The purple wire does route to the stator through the wiring connectors from the rectifier. My first thought was to leave unconnected, maybe I don't need it? I'd appreciate any experience anyone has with this issue. My manual doesn't cover missing purple wire from rectifier. I need a newer manual. Thanks
