Dead battery in ford sport trac

[hoppi]

I have a 2010 ford sport trac with 6 cyl 4x4. On my first long trip, the battery died. I had to jump start and recharge the battery. To unlock the steering, you have to have the ignition switch in off position 2. I now know that in that position, the radio (even in sync) is drawing current. My question is what else is drawing current that causes the battery to discharge. I also use a Brake Buddy, but on my return trip I used a separate battery for it and still had the dead battery in the Sport Trac. What can be done to keep the battery charged while being towed? Love my Sport Trac otherwise. Hoppi

Could be Both the Ignition setting or the Brake system...check your owners manual
may need to take a fuse out

Hi Hoppi, you might need to run a power wire from theMH to the toad. On mine I used the six pin coiled cord so I could use the 12 volt hot pin to tie into the battery. I use a similar set up with patriot brake. good luck!!
