2011 Buick Lacrosse tow car battery problems
My 2011 Buick Lacrosse battery dies after an hour of towing. This problem was in prior posts back in 2011. Wondering if anyone has found a solution to this problem? Dealership here just shrugs this...

I did have the power connector set up to give a trickle charge while in tow. This does not seem to work. I discussed the pulling of fuse option with the dealer, they said this could cause other problems...
..Not sure quite how you wired the 'trickle charge', but normally running a charge line is the easiest, cheapest, and most simple way to solve battery draining issues. I had exact same problem, and I solved it completely by running a charge line.
All you gotta do, really, is run a wire from + of your MH battery (usually already there on back of MH in the 7 pin connector) to the + terminal of toad battery. If you have an extra, unused pin/wire in the umbilical cord used for tail-lights, you can use that and won't have anything else to have to attach/unhook when hitching up. Just have to make sure the chare wire you run is fused both on the MH side as well as on toad side just before it goes to the battery. Ground (negative) should already be wired from your tail-light wiring. If not, you'll need to run a ground wire, too.
In many cases this will eliminate the need to have to pull any fuses. And, it eliminates any worry ever about ever running down your toad battery.
