Towed Ford Explorer Battery is Dead After A few Hours of Flat Towing Behind Itasca Motorhome


I have a 2014 itasca meridian and a 2013 Ford Explorer with the Invisibrake. The battery on the explorer is dead after a few hours of being toad. I had the dealership check it and showed as all charge back to the explorer. Why is my battery dying?


Expert Reply:

The Roadmaster InvisiBrake Supplemental Tow Bar Braking System # RM-8700 is designed to deliver a trickle charge from your running motorhome's electrical system to your toad's battery while you're underway. This power feed is dependent on good ground connections between both the motorhome and InvisiBrake, and between the InvisiBrake and the toad. You can check to make sure all electrical connections are sound and that there is no corrosion on connectors that might be impeding the charging current.

If you had your battery checked and its okay, then you may just need to pull fuses. Some vehicles do require you to pull fuses when flat towing to prevent battery discharge. If this requirement applies to your 2013 Explorer this should be noted in its owner's manual under the section entitled
'recreational towing'.
