Hey, nothing wrong with youtube for info and ideas. I will do it differently next time I replace the awnings though....
They have a newer model truck in the video. But according to the vid, the two batteries are connected together the minute you turn the key. With mine, there is a bit of electronics that only activates the solenoid when the alternator is putting out about 14.4 volts. (both items need replacing, the electronics and the solenoid)
