[QUOTE="Hanr3, post: 272544, member: 1055"] Not sure I follow. It is on a seperate fuse, 30 amp, which I have to install when I hook up the wire under the hood. Everything I looked at shows it is intended to recharge batteries in an RV. Based on the fact that it is a 10gauge wire Im assuming its not a quick charge, say less than an hour, but rather a longer charge, couple hours for a dead battery. What Im not sure about is how RV charge their batteries off teh 7 pin plug. Do they have a seperate charger which draws power off that pin? Dual alternator sounds great, however Im almost positive my truck came with a high output alternator. The truck came from the factory with the 7 pin connector prewired, receiver hitch, auxilary tranny cooler, and the wiring under the dash for a brake controller. To make all 7 pins work all I need to do is hook up that red battery wire under the hood, and install the brake controller. Towing capacity is about 6,000 pounds, not bad for a midsized SUV. Too bad GM stopped making them. I'm new to this 7 pin plug thing and still havent been able to find anything ont eh trailer end, specifically related to teh battery charging. [/QUOTE]
