Towed charger connection
We tow a Honda CRV never had a dead battery towing before. My friend tows a small Chevy suv and his battery goes dead towing, so we installed a RVI towed charger, nice little set up, so a couple of weeks ago coming home from San Diego it was a total of 8 hours towing, stopping half way to let idle for 5 min, got home put car in garage and next morning car turned over slow before starting. You can pull a fuse out when towing, but that’s a pain. So I ordered the same RVI towed charger my friend got so when it shows up I want to install it. It’s suppose to connect to a 12v key on only connection, Where does everyone connect in rear electric panel to a 12v keyed circuit, The unit has a in line fuse built in.

Art, we towed two Honda CR-V’s (2007 and a 2013). Honda required that we pull a fuse to turn off the Navigation system. As you know, you have to be on the staff of Cirque du Soleil to be able to reach that fuse.
So, on both Honda’s, I had them run a cut-off switch to that fuse and install the switch on the dash. It was so easy just to turn off that switch when towing. There are a couple of unused panels on the dashboard where the switch can be install (looks almost factory). Honda batteries really don’t last long (3 yrs. ?).
Seems like a cut-off switch would be easier than connecting anything to the coach.
Safe travels,
Mark

Wouldn’t it be cheaper and easier to run a power line from the 12 volt side of the chassis batteries to the toad?
I have two batteries in my stacker trailer which are charged in this fashion.

I charge my toad battery, or trailer batteries, while towing via the #4(1:30 position) pin of the 7 pin trailer plug. This is true with any vehicle I tow with.

Hey Don I don’t have a 7 prong it has a 6 prong and just lights go through it.

We’re towing our second Chevy HHR. I have to pull a fuse too because we tow with the key in the “on” position.
I too have wondered why can’t the “hot wire” from the coach be wired to the positive post on the battery with a fuse in the line.
I too have both the coach and the Suburban provide power (via the 7-prong RV plug) in the enclosed race trailer for the battery that powers the winch in the trailer (and since Monday) the electric tongue jack. Not sure why that hot wire can’t keep the TOAD battery charged.

Art,
Pic 1 is the 7 prong male flexi-cord that goes between the bus and the toad.
Pic 2 is the 7 prong female plug on the back of our bus.
Pic 3 is the 7 prong female plug on the front of our toad.
Pic 4 is the 7 prong female plug on the back of our Yukon. -
I put the charger on a little while ago, not todifficult. There is 2 led’s on charger 1 for towed and other for coach, Plugged it in to car and coach and the blue led is flashing for car says battery good started bus and the other was flashing green means charging, when battery is charged #2 led stops flashing, so it just charges when necessary, pretty simple. I tied on to bus in rear compartment.
