08 Pathfinder, charging RV battery via 7 pin?
08 Pathfinder, charging RV battery via 7 pin?
Hi, replaced my 4 pin with a 7 pin round, genuine Nissan part for my RV. Easily attached to hitch and plugged in near rear tire. Trailer brakes work fine(via controller and harness under dash), trailer lights work also. I was told that when I am towing my trailer, the Pathy should also be charging the 12 volt battery on my camper, but it does not seem to be charging? Did I miss something?

Is the trailer battery wired to the trailer's hitch plug?

Not sure, I will have to check. Trailer is not stored at home, will have to go over and see. All I know is that there is only one wire for each terminal on battery, and not sure where those pos and neg wires go to in trailer, I will have to check it out.

Here's a picture: http://rides.webshots.com/phot...oyJin
The +side of BOTH batteries needs to get to pin 4 on that side, the - side ofBOTH batteries needs to get to pin 1. The key to locating the pins is thenotch shown in the bottom of the picture -- it MAY not be at the bottom on your truck.
And the connections need to be pretty heavy gauge wire. The usual 18 gacrap used to wire trailers won't come close and will go up in smoke thefirst time you fire it up with low trailer battery. If you have a fresh truckbattery and a tired trailer battery, you could easily pump 100A down thatwire. 100A requires 6 ga in the marine world, and marine wire is more capable than the stuff from the auto parts store (bigger cross section andsmaler strands (less air)).
Someplace I'm pretty sure I've seen a 12V in 12V out charger for just yourpurpose. It regulates the current so you can use lighter wiring. I lookedat it for my boat, but since there was no easy way to get wire over the bowto the truck, I just got Schumacher smart trickle charger. The boat goes onit as soon as it gets pulled into the garage. They are great for occasionallyused verhicles --- the 'vette got like 10 years out of a battery, driven a fewhundred miles a year, and living on a Schumacher.
