2012 CRV charge line

When pulling the CRV toad, we have to stop every 4 hours and start the engine to charge the battery. Anybody pulling a CRV - Can you tell where your toad charge line comes from and where you hook it to on the CRV? It's been a pain and leaving soon from Ohio to Florida to pick up our new Anthem 44B. Bye bye Monaco

We tow an '05 Ody and had the same problem. I added the charge line and have had no more problems
Wired from the battery disconnect in the engine compartment through the 7 pin plug, through the 6 conductor wire to the Ody battery. I also use 30 amp automotive self resetting breakers at both ends of the wiring. You also have to make sure you have a good ground wire. Don't depend on the hitch to provide a good ground, needs to be hard wired.

Kerry Buchen-

It's unclear to me... Do you want to add a charge line to your Monaco, or to your new Entegra?

Monaco goes bye bye. But the problem remains, regardless of the coach. I have to turn the ignition key to the on position to unlock the steering wheel.

There are a few posts regarding dead battery on the CRV. Install of a charge line is one thing but the real issue with the CRV is that the OEM battery is grossly undersized.
Even if you install the charge line, I suggest you go to your Honda dealer and purchase a two piece plastic battery box for a 2012/13 Oddesy. Remove the group 24, 400 CCA battery and replace it with an 800+ CCA battery. Your dead battery problems will be gone. This is a bolt in procedure. No mods required.
I fought with this for the first year I owned mine. Honda tested the battery and charge system on two occasions and said everything was good. Finally I had enough and made the switch. Now I can travel for two days without disconnecting, starting in the AM for a few minutes to lube the transmission, and have not had a dead battery.
If you do choose to install a charge line, it is a fairly simple deal.
Take a connection off the chassis cutoff switch on the MH and into the Aux pin on the 7 pin connector. On the toad end run a wire from this terminal to the pos post on the battery. Use a 20A fuse on the MH and Toad end for protection.

I don't have a CRV, but I hooked up a charge line to our towed. It is a pretty simple process. The 7 pin connection at the back of your coach will have one terminal that is 12 v power from the chassis batteries. You just need to connect that through your towed vehicle connections and to the positive post of the towed vehicle battery. Pretty straight forward.

Kerry,

Your new Anthem will come with a fused charge line from the 7 pin connector. From your plug on the CRV run a charge wire (at least 14 gauge) to your battery area. Don't forget to fuse the battery end (20 amp). If the fuse is not the resettable type do not start the car with the cable plugged into the motorhome, if you do it will draw enough through the charge line to blow the fuse.

You can buy a fuse disconnect on line. I used one on our CRAB

Get a fuse disconnect. I used one on our Honda and it worked great. I mounted the switch in the little change tray to the left of the steering wheel. We now have a mkx which will require a charge line. It is flat tolerable but there is no info on the battery situation and it discharged after 2 days. Good thing I had a charger and extension cords in the coach. They do not make a fuse disconnect for the mkx.

Hi,
On my Roadmaster Falcon All-Terrain tow bar the Park / Running lights send power to trickle charge the Toad through the brake light etc. cable pin #7 I believe.. I usually just drive with my lights on anyway and I added a "Headlights are still on" alarm to remind me to turn them off after turning the engine off. Check your Tow Package owners manual to see if yours requires the lights to be on or not.

Rich

I pull a 2013 Honda CR-V and had problems with flat batteries when pulling the CR-V with my Dynasty. However, the problem really is the lousy battery that came with the Honda. I replaced the OEM battery the third time the battery was flat after 3 or 4 hours of towing. Now, I pull the same CR-V for 8 hours following the standard Honda procedure.... (no charge line) I stop every 8 hours to run the Honda following Honda's specified flat towing procedure, but the battery has never failed since the new battery was installed.

I use an Air Force One toad braking system which consumes very little power. But an 8 hour tow is not a problem with this system and a good battery.

I'm not denying that the CR-V's battery should be upgraded, but putting in a charge line resolves the problem, anyway. I'm using a ToadCharge kit because it has an electronic switch that prevents the MH's battery from charging the toad unless the MH engine is running. It also has a circuit breaker to protect both vehicles.

Don't assume that the 7-pin connector on your MH has a 12V connection; mine doesn't. I ran a pair of conductors from the MH's battery along the umbilical cable to the CR-V. I used zip-ties to tie the new wire to the existing cable.

Remember, even if you install a larger battery in the CR-V drawing it down each time you tow doesn't do anything good for the battery. Having a charging wire prevents it from being drawn down.

I don't see how people can blame the battery in the CR-V. The battery works fine for many years when not being towed. It's only when you tow it that the battery becomes a problem. Nothing wrong with the battery or it's size, just people are using it for something it's not designed for.


Even the much bigger battery in our Ody is discharged in a day or so. Since adding the charge line works fine. On a 7 pin plug it's #4 that is the hot one if you follow the standard wiring diagram.
