Hello all. I have heard & was wondering if anyone out here can maybe give some detailed instructions on possibly using my wireing harness to recharge auxilary batteries in my Trailer. I have 2 Marine batteries I use an inverter on & I heard that it was easily possible to use my trucks alternator (a pin on the 7 wire plug already) to charge the batteries in my trailer while I am driving (I currantly use my battery canrger at home & then take with me) to keep them charged up. Does anyoine know how this would be possible & what I would need to accomplish this little task? If my truck is already wired from my alternator to the 7 pin (someplace) It does sound like it would not take too much. Anyone have the know how to do this for me? Thanks everyone.
