I'm still not certain what our next step should be.  Do we just attach a single wire to a connection inside of the CR-V's wiring socket that will extend the 12v line to the CR-V's positive battery post, or do we also need to connect a wire to the negative lead to extended it to the CR-V's negative battery post or to ground?


If I type fast, I can beat Ron on this one.  Use a single wire from the socket to the positive battery post.  Ford uses 12 gauge wire for this circuit so you should continue with that gauge.  There is a fuse in line in the fuse box under the hood that protects the circuit.

Bob did beat me so I am left to say.....Sounds right by me.

Bob, Just clarifying...."fuse in line in the fuse box" You are referring to protection in the PC.

Bruce, the ground wire should already be in place to support lighting like tail lights and directional signals.  I would not worry about the ground wire gauge because the setup most likely considers battery maintenance.

In my 2007 rig, I do wonder if there is an accessory or two (or 3 or 4) installed by PC USA sourced off that ignition-on-12v to tow vehicle.  It would explain my situation, and might be the case with you guys too.  You just don't know it yet.

That is a great start.  I hope it is also your finish.

Whoever installs your rear bar and helper springs, have him inspect the front stabilizer bar.  Just make sure it's in good order, especially where the ends of the bar passes through gromets.  Get the mechanic's opinion on that.

Bob, I understand your point and surely take no offense at all.

You are both working with newer rigs which might be the reason for the descrepency.  In my case with our 2007 E350 chassis while towing, when everything is turned off, shut down, and parked for the night, my tow vehicle 12V battery power is finding it's way back into my PC, lighting up things there on the PC.  I always thought my rig was setup as you described with relay protection and such, but this is what happens with my 2007.  I cannot rule out that something is quirky with my Jeep Liberty or my wiring of my Unified tow brake.

Like I said before, it's been 4 years since towing overnight and I can't recall the details of it all.  I just remember needing to unplug the coily to turn off everything to prevent the tow vehicle battery from draining overnight.  The next time I tow overnight, I'll have to document exactly what's energized, what's lighting up.

Hopefully all of you with newer chassis, different tow vehicles, different tow brakes, don't have my power ghost.

If we find any of the six connectors empty there (and they will match up to the 12v pins of the coily cable), do we just add wires there that will run directly to the towd's battery posts to complete the battery maintenance feature?
I believe you are correct.  I think it is that simple.  But keep in-mind of my story one reply higher.  You might need to unplug the coily cable from either end when parked for the night.  The alternative would be to add a diode in that 12V hot wire inside the tow vehicle so 12V will travel from your PC to the tow vehicle's battery, but not from the T.V. back to your PC.

I agree that the industry has nailed down the frame extension process so I would get whatever floor plan I wanted, stretched frame or not.

But still there is a little peace of mind that our 2350 has an unmodified 158" wheel base.  It's nice to know that all parts are stock/generic.  For example, if I needed a parking brake cable, a brake line, a fuel line, drive shaft, whatever, on a trip, I know the shop in No-Where USA can get a Ford stock part right away, rather than fabricating something to get me back on the road.

The family is growing!!

I Love It!

In all our travels, I've seen only a couple PCs.  Apparently we go were few PCs travel.

Last August, a woman approached us in Glacier NP in the Many Glacier Hotel area saying they too own a PC but it was at their camp site.  We showed her our unit inside.  We later went to visit them but there was a long line of vehicles waiting to enter the camp ground there at Saint Mary's so we turned around and got out of the jamb, back to our site at Rising Sun CG.

Who was that woman?  I thought it was the wife of someone here.

Hi Bruce,

It's good that you've got the standard 6 pin setup.  That resolves much.

As you have said, none of us here knows how Camping World wired things in your Tow-Vehicle/CRV .

You mentioned having a multi-meter so I suggest you probe a few simple things to see where you are at.

I think I gave you some bad information as to that 2 pin diode.  I read through my Unified tow brake installation instructions and they call it a circuit breaker, not a diode.  So the 2 pin rectangular box is there for protection, not for one-way voltage.

So with that given bit of information, try this with your setup.

- With coily cable plugged into PC with PC ignition switch on or motor running, but not plugged into the tow vehicle, probe each pin on the tow vehicle end of the coily cable to confirm you are getting a constant 12v from the pin there that is equivalent to pin #4 on the PC.

- Identify the mating pin inside the socket on your tow vehicle and mark it somehow so you can easily identify it later.

- Now probe all the pins in the socket of your tow vehicle with ignition on (and then off) and see what you get.  You might have one hot lead.

Hopefully that hot lead is the same hot lead on the coily cable.  If that is your case, then you are already setup for the tow vehicle battery getting maintained by the PC when being towed.  

NOW THAT I THINK ABOUT IT  (I think I suffer from an over-load of data in my head)
When we've towed our Jeep Liberty (it's been 4 years since the following condition), I recall that when we've stopped for the night in a Walmart or rest area with tow vehicle hooked up, with everything shut off, some things were still activated, though I can't recall what.  I remembering the need to unplug the coily cable at either end to completely kill all power to all things for the night.  That is one possible explanation why your tow vehicle battery is getting drained.

I think that is why the "Diode Thing" was in my head, thinking I'd like to add one to eliminate that condition.

Does all this make sense?  Let us know what you find.

I called Zone Defense and left a message.  A tech guy called me back.  He said there is a pin hole in the back of the camera.  As I suspected, he suspects too, the pin hole is clogged with dirt or other foreign matter.  I'll have to dismount it to clean the hole.  Then hopefully I'll have sound again.

I also asked about the LEDs.  He says they are IR LEDs.  The naked eye won't see the light, but the camera picks up the images in the dark.  That explains how I could see in the monitor, my wife walking around behind the rig in the dark.
1494  Main Forum / General Discussion / Re: I killed my carburetor on the Onan Generator on: October 15, 2013, 10:16:44 am
Here I go again with a different opinion.....down goes my helpful rating, 173 at the moment.

I have a hard time buying the "Varnish" condition.  Today's fuels evaporate in the carb leaving no varnish, almost no residue of any kind.  This because of the detergents added for fuel injection and the 10%-15% ethonol content in all fuel.

I won't start my PC generator for a year at a time and it starts up.  Yes hard to start at first, runs rough for a little while, then smooths out and all is well for the season.

The same goes for my 24 year old 18hp lawn tractor, 8 hp snow blower, and 8 hp roto-tiller.  I never do any with my carbureted lawn/yard equipment when put away for the season.

Keep in-mind my off-season storage is indoors for everything except for the snow blower.  That stays outside off-season in a storage shed, yet still runs perfectly fine when I wake it up.

Back to the PC generator, I can't imagine the carb going bad from lack of use.  I don't know how to feel about the generator portion considering outdoor storage.  That is a different subject matter.

Tom, I was cleaning up my reply when you posted.  You are correct in that the socket at the tow vehicle needs to mate with the coily cable you buy.  So if replacing the coily cable, get the mating socket too.

There are at least two flavors of coily cables.  All have the same style connector by the PC that looks like this.  (note that this example has only 4 metal terminals)

The difference is at the other end by the tow vehicle having 4, 6, or 7 terminals.  If you have 6 or 7 terminals, then 12V from the PC is right there where you need it.  You'll only have to run a wire a few feet from that connector on your tow vehicle through the rectangular 2 terminal diode, then to your tow vehicle battery.  It is a very easy modification for someone who knows what they are doing.

This is the end of a 6 terminal coily cable.  You need at least this many terminals.  If you have this you are in great shape.

Here is a 4 terminal coily cable end.  If you have this one, you'll need to replace it and the socket at the tow vehicle.

Another approach might be to add a charging line from our coach back to the Honda battery, but that seems to be much more difficult.  Any ideas?  Bruce
I believe it is quite easy to wire the tow vehicle into the PC 12V system for battery maintenance.  Power from the PC to the tow vehicle battery is run directly through the main red coily cable in my picture, which includes brake, tail, and turn signal lighting.

My Unified tow brake system diagram HERE does exactly as you describe.  I would follow the diagram 12V battery portion alone.  Just ignore the majority of the wiring diagram.  It should be extremely simple.  I believe the 2 terminal box is a diode, but I would need to confirm that.  You'll need only one (assumed diode) in the tow vehicle.  The other in the motor home is not needed because the PC is pre-wired, ready to tap 12V power at the connector in back.

Here is the diagram of the PC connector, an industry standard connector.
Terminal #4 would be the one to use for tow vehicle battery maintenance.

Here is an example of my wire harness.  One end mates into the PC, the other with round terminals, plugs into the tow vehicle.

It is seamless, very easy once setup properly.

The manual had an email address for questions but it bounced back today.

Thanks for the phone numbers.  I will try them Monday.

Oh yes indeed.  That is why I moved it here.  If you look close, you can see where it used to be on the headliner.  One day I'd like to mount a low profile cubby for little things to store and to cover up that hole.

My ZD manual is too basic.  It doesn't offer anything of value.  The book says it's System 322.  It implies the microphone is in the camera but I can't find it in that little thing.
