Recently while towing Acura with Blue Ox package, I told my spouse that I was going to check car. Opening the door I immediately noticed that the lights didn't come on and the binging from key left in ignition didn't sound. Battery was dead. Disconnected car from Sightseer and jump started car. I noticed that brake lights didn't work when I hooked it up, but didn't have time to trouble-shoot. What now?
