Thanks to the fine folks on HTW I learn a bit more about my trailer everyday. My trailer batteries are 4 years old and dead, they will not take a charge. Last year I just ran my generator and at times ran the LQ off of the pickup battery. Based on the responses I got to a post on this forum I don't think that is a good idea (running the LQ off the pickup) and therefore I am going to replace my batteries. My issue is this, I have a 2009 Dodge Ram and the aux power to the trailer through the 7 pin connector remains hot even when the pickup key is on the off position...in other words all of the time. My concern is that even if I add batteries to the trailer there seems to be no system in place that keeps the LQ from pulling from both the trailer and the pickup batteries. I have looked into battery isolaters but that doesn't seem like it would solve my concern, it would still allow power to flow in one direction (ie pickup to trailer). From what I can tell the wiring of the 7 pin connector has a black wire that is an auxillary wire which is always hot (on my pickup) and basically charges the battery and powers the 12v in the trailer. I could just unplug the trailer from the pickup each time we are at a show but then I run the risk of leaving a show without lights and brakes becuase I forgot to hook it up, I would like a more eloquent solution than this. My question is this, is there anyway I can be assured that the trailer will not pull power from the pickup battery when it is connected to the pickup and has fully charged batteries (on the trailer)? If not is there any problem with just disconnecting the aux wire from the plug to the trailer? As far as I know it's only function is to charge the LQ battery and power the trailer from the pickup battery. I have a battery tender on my trailer so that is covered and obviously the LQ batteries would power the trailer so that is covered. Any input is appreciated. |
