I just finished a 1500 mile journey in my 40 FDQS 2005. Running 5-6 hours some days. My toad battery died and needed to be jumped consistently . All systems were turned off in the car , a 2010 Lincoln MKX. Is there a way to have the coach system keep the charge up?

I use the Toad charge from lslproducts.net.....works just fine.

You can have your toad battery wired up to the MHs alternator and that will do the trick.

Cant speak to your MKX--sure someone can, but often, toads require a fuse to be pulled, or the battery disconnected via a blade switch to prevent battery discharge. Before I went to the bother of buying and installing a "kit" [fused] to connect the toad to the MH, think I'd consider the pros/cons of correcting the toad's discharge issue first.

X2, sometimes you can turn the ignition switch an extra click beyone releasing the steering lock and it will power some accessories, been there done that

Would not recommend disconnecting the battery. I believe your owners manual states to leave the Ignition in the ACC position for towing.

I assume your rig is a DP so, you can run a wire off the Master Chassis Switch, through a fuse, to the 7 pin plug on the MH. I believe the 1: o'clock pin is used for this purpose. 20A fuse is most common. Some use an auto rest breaker. You're choice.
Now at the toad end, run a wire from this connection through a fuse to the toad battery.
While the MH engine is running, it charges your toad battery. If there is a problem at either end of this line, it will blow the fuse.

Still suggest you stop every 4 hours or so to start the car and idle for a few minutes to circulate oil through the transmission.

Question here on wiring the TOAD battery to the coach's charging system thru the 7 pin connector. What keeps you from over charging the TOADS battery with the MH's charging system. Assuming you start with a fully charged TOAD battery the MH's batteries will be down from starting the coach, so the alternator will be putting out approx. 14v+ to recharge the MH's battery, Won't this overcharge and boil the TOADS battery?

Short answer, No.
The amount of current delivered through the wire between the coach and the toad is not enough to overcharge the toad battery. It will be barely enough to maintain a charge on the battery given the loads applied during towing.

I read on another forum the guy had the same car and year. Said to start car and put in neutral while you are hooking up then turn the switch back towards acc as far as it would go.
