Towing 2012 Ford Focus

[Towing 2012 Ford Focus]

We tow a 2012 Ford Focus with a 2002 32 ft Winnebago Adverturer. So far no Problems. Have towed around 1300 miles.

We disconnect the negative battery cable not at the Battery end but the other end of the cable where it bolts to the firewall. We use a 3/8 ratchet with a 1/2 inch deep socket.We then slip a piece on foam rubber pipe insulation over the loose cable.It is simple and it works.The only problem we had was after a long day of towing, when the car was unhooked and started the transmission smelled hot. It was just once and we have not smelled it since.

Hope this helps. IF you have any further questions just ask.

Thank you

Steve

But by disconnecting the fender end of the negative ground wire, you are not disconnecting the battery. The battery is still grounded by 3 wires coming from the BMS (Battery Management System) module still attached at the negative end of the battery and therefore to your car with 3 seperate wires in a shielded cover. I believe these go to the engine, car body and alt. The module that they come from has letters and numbers stamped on it like Fomoco C95Y0 SW 2 21 and

AV6N 10C679 88.

May be why there was a hot smell looming the first time out. Just a thought...

Maybe Wolfe 10 can help us out here with some info on this module and 3 wires on the negative battery post end of the battery cable on the 2012 ford focus. Purpose, function and where they go and why.

Sorry, I prefer to feed the toad battery off the coach battery when the coach is running. Many toad ECM's get cranky when continually disconnected from power.

Running one extra wire, two fuses and a relay is a more reliable way to go.

I have a 2012 Ford Focus and just having it set up (baseplate and towbar) for towing. Please explain about the "extra wire" thing. I may be interested in following suit on that idea. Thanks for any advise. I have a 37' 2000 National V-10.
