We were dry camping last weekend and accidentally ran our batteries down in the ffx. We had two vehicles with us, a Tahoe and a Jeep Wrangler. Both vehicles have the 7pin round connector and are supposed to be fully wired.
In the morning, I started the Tahoe, connected the cable to it and checked the power in camper, still dead.
I then connected up to the jeep and was able to pull power from the battery of the jeep while running.
So is my Tahoe not wired up correctly? Its not allowing the trailer to draw immediately usable power from its battery, while the jeep does.
As a side note, the Tahoe does charge the trailer batteries over time, it just doesn't give me immediate access to the battery.
Any thoughts or suggestions appreciated
