Why is my car battery going dead.

After a day of towing my Lincoln MKT behind my coach the battery goes dead in the car. Why?

Do you have to leave the key on?? If so do you pull any fuses. What type of brake lights do you have, do they rely on the coach battery or vehicle battery.

I have a Jeep GC, I do not leave the key on or have to pull any fuses. Usually I don't have a problem but last year we towed the Jeep for 3 days straight. The brake lights are the only thing consuming power but after 3 days the battery had to be jumped to start the Jeep.

Several things:
What toad braking system are you using? Some systems use the toads battery to operate, and then when the toad brake is activated, toad battery current can illuminate brake lights.

Do you have to leave the ignition key in a ON position? if so, certain electronics are activated.

To overcome this, you need to install a "Charge Line" from the coach to the toad. Relatively easy to do depending on what chassis you have and what trailer plug the coach has.

The car just has a key fob . I put it in nuetral. No brake toad system. Wired from the coach trailer plug to the car wiring direct to rear lite wiring. Only lite on in car says place car in park. 2017 Lincoln.

Did you read the factory info on towing the vehicle? You will probably find your answer there!

I was having this problem intermittently. I later found the root cause but in the meantime I added on of these to the coach/toad wiring harness:

Generally to get any newer car in neutral, you have to turn the key to the on position. That also unlocks the steering wheel. If the key will not turn back to the left (and still keep the steering wheel unlocked), then you are powering up several functions in the car that you may not even be aware of. That will cause the battery to drain.

As mentioned in a number of threads on this board, you need to get a towed vehicle battery maintainer. I'm actually installing a unit on my RAV4 today. I got it from Amazon for about $22.

It's just a current steering diode, a fuse, and a couple of wires in a small enclosure.

With the key less ignition system and shutting down the engine with the transmission in neutral rather than park there are probably multiple systems still active that are draining the battery such as the Sync, Nav, inverter or the radio just to name a few. The owners manual guidelines state to remove the negative lead from the battery. If disconnecting the battery isn't something you want to add to your pre-drive check list then adding a charge line from the coach is about your only option. You could pull fuses but with such a new vehicle and a small group of users who tow a MKT, and are will to experiment to figure out which fuses, your options are pretty limited.
