2017 Silverado 2500 Truck Battery Isolated?
When the ignition is OFF on my 2017 Silverado 2500 Durmax and tow package equipped truck, will the charging cable that runs back to the trailer be automatically disconnected so that the truck battery is protected from being discharged? Or do I need to add a relay or some type of battery isolation kit to protect the truck battery from discharge if the trailer to truck plug is left connected?
