Flat towing my JK

Is it necessary to disconnect my battery when flat towing my JK? I saw a battery disconnect online and the company says MOPAR recommends it. I looked through the owners manual, not the DVD, and could not find any information.

Any help??

Thanks

Mine is a 2013. Didn't see that recommendation. I'll check again tonight. Thanks.

I flat tow my '12 all the time and do not disconnect the battery. I had a disconnect added but dont use it. Towed it this past weekend 5 hours and no issues.

Why? The key is not even in the ignition. Electrically, it is no different than parking it in the driveway.

Not exactly. Keeping the battery connected does keep power going to certain things whether the key is on or off.


I don't know why they would suggest removing the key though. I don't know what is getting power that is better off without it while the Jeep is rolling down the road.

I forgot about that. The key needs to be turned on to keep the steering lock from engaging. That will drain a battery on a long trip.

I guess they deleted the steering lock on the newer ones though, and i have a 2008. My steering lock doesnt work 90% of the time though, which is why i said sort of.

I never paid attention to the steering lock on mine.

I flat tow my 12 and do not disconect the battery. The owner's manual says to, but then I have no power to the turnsignals and brake lights. I have a small battery charger and I plug it in at night about every third night if towing and never driving the Jeep. No problems so far.

if youre using a 7 pin round connector, which has a +12v line to charge campers, theres a more automatic way to do that.

There are several options for brake and signal lights, but this is the one I use. It has the advantage of being totally independent of your Jeeps electrical system, thereby negating any need for power, diodes, keys in the ignition, warranty concerns etc. It is a simple install. I have been towing cars for years now, spent a small fortune on various approaches, and I have come around to simple is best. The ReadyBrake and this kit is about as simple as it gets.
