That Black Wire???
Okay, so in the 7 blade pigtail there is an aux/power line (black) that runs to the battery charger in the trailer and I suppose that helps maintain the battery and supplies power to the rv when on the road and hooked to the tow vechicle.
My question is, to supply power to that circuit do I run a hot wire straight from the tow vehicle batter or does that wire need to come off the alternator?
I'm guessing that if I'm running off the battery in the tow vehicle it really won't make any difference. The only thing I really am unsure about is whether or not I should have a circuit breaker in that line?
Any response is a good one, thanks guys!
