Just hooked up my duel axle trailer (has been parked for a year). Could not get a gain on the trailer brake control.
Checked battery on the trailer. Only 7 volts. Need to get a new battery. Question-if this battery is dead would it affect getting the gain control to work in the truck ??
Thanks for any feedback. This TB-LT is great !
