Plug in chargers vs solar panel polarity
As I stated in a previous post a while ago I ruined a lawn tractor battery by using a plug in charger pig tail with a solar charger. Can anyone explain why they have different polarities for plug in and solar pig tails? Pig tails are opposite polarity, you would think there would be a standard. My Battery Tender model identifies polarity so you can plug any configuration into it but the YUSA model is specific and my two solar chargers are specific but opposite from the YUSA.
