Tow vehicle battery going dead

Flat towing a 2007 Honda Civic, with no problems except one.
The running lights stay on and the battery goes dead after about two hours.

Any ideas..on how to prevent this? The ignition must stay in accessories potion, and in neutral.

I have heard of a tow charge? How much

Thank you

    How old is car battery? Maybe the easy way to fix problem.

    you must not be mechanically orientated? even a new battery would be pretty low after leaving the lites on for 2 hours never mind what else is powered up when key is on
    as other have posted lots of ways to counteract the problem.Cheapest and easiest is take the neg battery cable off while towing
    all u do is need to reset the clock and any saved radio stations

    Merleandbabe, if your running lights are on you have the ignition switch turned one notch too many. With the key in the 'off' position, slowly turn it just one notch. You should be in the accessory position with no running lights.

    Good luck,

  • As mentioned above...pull the fuse. There are "inline switches" available online that allow you to pull the fuse and replace it with a circuit that has a switch and an inline fuse. You can mount the switch anywhere under the dash. When you want to tow, either pull your existing fuse, or upgrade to the switch and just flip the switch. That kills power to your dash/ignition/etc, but will leave your clock and radio alone.

  • I have a PT Cruiser I use and all my mechanic did was add a disconnect screw to the negative battery cable. You just unscrew it and you are disconnected, screw it back in and you are ready to go. It takes about 5 seconds to do. Cannot remember cost had to be less than $30.
