End of last year started having some trouble with trolling motor cutting in and out. I replaced the plug but not the receptacle and it appeared to work fine for a couple of trips. Started out this year and had a little trouble on the first trip out with trolling motor being intermittent again.
Do I just need to strip some wire off the negative end and reattach? or do I need to add new receptacle and plug? as you can see from photos it has charring and pretty corroded.(assuming years of moisture got to it?)
