Hopefully someone else has viewed the videos and will be answering up soon.



On Edit. I just looked at etrailer. Any of these help you?

Thanks Donna! I've viewed about a dozen vids and couldn't find the one specified. I think I'm going to have it done by a pro along with the rest of my tow package. By the time i get there I'll be well prepared from reading FGRV posts to be a very well informed consumer

Lighted Switch

I added a switch to my tow vehicle's dashboard. It's used to connect the positive side of the Tow Vehicle's battery to the trailer's battery thru the trailer connector. The switch has a blue light that comes on when the switch is on.

I only turn on the switch after the tow vehicle's is in motion and turn it off before I stop the tow vehicle.

Very easy to do. I also put a fuse in series with the Tow Vehicle's battery.

The same thing happened to me. I thought, oh oh, big bucks going out to fix. My friend came over to help me investigate. I had done all the things you had. The battery did not charge when plugged in at home, and I had no shore power going to the unit either. The circuit breakers all look like they were "on", he just turned them off and back on again. Viola!!! Power!!! Not sure if I hit something and the unit bounced a certain way when I was coming home and caused it to do that or what. But it works now.

I've installed a voltmeter and ampmeter on my camper's battery; I have found if every connection between the camper battery and tow vehicle battery isn't perfect, you won't get much of a charge from the tow vehicle.

Mark: This is off the subject but, tell me about the paint job on your camper. It looks fantastic. What did you use and how. Thanks Mike

Generator in my TV is powerful enough, 12V charge circuit is done with gauge 10 wire, so I have no problem with charging the battery and running RM2193 refrigerator while driving. The bigger issue to me was battery discharge when stopping at rest areas, shopping plazas etc. RM2193 12v heater element takes almost 10A, it's high enough current for group 24 battery, battery voltage with this load quickly drops to 11+ volts. I suspect 20-30 minutes stop takes more juice out of the battery than 1-2 hour charging while driving.

To resolve the issue I installed low voltage disconnect circuit to refrigirator's 12V supply line. It disconnects power from refrigerator when voltage drops below 12.3V and turns on again when the voltage is above 12.8V. So refrigerator runs only when TV's engine is on. Works perfect to me. I bought LVD circuit on ebay for about $15.

7pin wiring

We have a 07 Sequoia without a tow package bet we had installed a bargeman 7 pin connector Only 5 pins are working It's hooked up to trailer a boat with disc brakes I'm missing the brake and charging circuits .
I didn't realize I could take the power off the 12 volt plug in back of vehicle .I'm going with a prodigy RF unit that does not need the brake component just need the charging circuit . I will look at 12 volt in back see if it's strong enough 12g ? Thanks for any advice Jim

Hi Jim, I had a 7 amp load plugged into the "12v power port" aka cigarette lighter socket in the back of my Jeep. After ten minutes it was too hot to touch.

Run a dedicated wire with self reset 30A fuse from battery to the 7 pin connector, do not re-use existing 12v socket.

The best way to determine the adequacy of a already installed charging system between the tow vehicle & trailer is to actually measure the charging current under normal conditions. Find someone with a clamp on DC amp meter (Sears sells a relatively inexpensive one that is also a multimeter that can measure resistance & voltage).

With the tow vehicle connected & the refrigerator on 12V DC, run the engine at your normal driving RPM & put the clamp on meter around the wire going to the #4 pin on the 7 pin connector. If the current is equal to or over the refrigerator's draw, you system is adequate. If not, then improving the wiring is worth doing if you plan to run the refrigerator on 12V while driving.

While measuring voltage gives you some idea of the charging system, it is not alway accurate since it depends on the the state of charge of both vehicle's batteries and other variables. The amperage measurement is more accurate.

I also suggest checking that the tow vehicle connection shuts off with the ignition. Some do, and some don't. A inexpensive solenoid can be added that will do it automatically, saving remembering to unplug during long stops.

07 Sequoia

Thanks Denny ,and the rest for helping .I will run a 10ga wire from battery with 30 amp fuse and put solenoid where?

Denny we sold the Snoozy will be buying a 21 ft Escape a little more room for Grandkids and it has all the options I was going to do to Snoozy. hope all is well Jim

..
etrailer has many guides on the topic, such as:
https://www.etrailer.com/question-18098.html

There might be one more specific to your case but many are similar.

You MIGHT be able to use the 12 volt socket in the rear of the tug to control the solenoid but not supply the actually charging current, assuming the socket is "on" only when the engine is running. If your charge wire is run under the tug as most are you would need a wire from the socket to the solenoid somewhere near the charge wire but the best location is vehicle dependent.
