Does Battery Have to be Disconnected to Flat Tow a 2015 Ford Edge Behind a Motor Home


The manual says that you have to disconnect the negative battery cable. Is this required only to keep the battery from becoming discharged? If so, can a battery charge line be used from the moter home instead of disconnecting the battery. I've also seen a fuse shutoff for the Edge, is this another option?


Expert Reply:

The negative battery cable does need to be disconnected to flat tow your 2015 Ford Edge and it is because otherwise it would drain the battery. There is a way to provide a maintenance charge to the battery but it will not charge up the battery and the battery could still drain. You can also add a battery disconnect, # RM-766, to make it easier.

Roadmaster has a charge line kit, # RM-156-25, that will work with your Edge. It'll help maintain charge but, like I mentioned, won't actually charge the battery up.

A fuse bypass is needed on vehicles that have to have a fuse pulled in order to flat tow the vehicle. Consult your owners manual for more information on any fuses that have to be pulled on your Edge. A fuse bypass does not replace removing the negative battery cable though. It just makes removing power to a fuse easier. Disconnecting the battery would remove power to the whole vehicle.
