It depends on the resistance- it will draw from the higher voltage source until the resistance in the circuit gets high enough the voltage drops to equal the battery voltage.
I believe you're over thinking this, and that the instructions are not very good- they spec a "25 to 40 amp" feed, and recommend using #12 wire. 25 amp would call for #10, and 40 amp would call for #8 minimum, purely on load carrying capacity (ignoring voltage drop).
I wouldn't sweat it- just make sure the factory circuit is in good shape, the plug is clean, and all connection tight.
so am I over thinking it, or are the instructions not very good ;) ?
i hear you. the guy at e-trailer seemed to think I was the first one who read the instructions and thought of this. i'll see if I blow the fuse....
Thanks again for all the thoughts. Taking it out this weekend, I will update...
