Our F150 light switch needs to be set on the second last position to power the trailer lights. Won't work on Auto. Okay.
When the truck is shut off, there is no power at all going to the trailer. I am guessing this is normal? On my old Sub, there was power to the trailer if it was plugged in. I had two batteries in the Sub and would just isolate one to be sure I had starting juice. The trailer has two 12v in parallel, so not too much to worry about for an overnighter.
Any ideas or observations on this, or is that the way it is, nothing more can be said?
Thanks in advance.
