ok i am posting on behalf of a family member, they bought a battery isolator and has it mostly wired and figured out, so my question comes down to if anybody has wired one up before, it has 4 posts, 1 is alt in, 2 are battery outs, and the 4th one is a sense wire.. the directions that came with it are extremely generic and gives no information nor does emailing thier tech support, it says to run a fused wire from the sense post to a acc/key on hot fuse panel slot.. i was wondering if there is a wire coming directly off the alt that would fit that bill... if so which one would be tied into for that one... any help is appreciated.

 

ok guys you can cancell the request for help... we got it figured out.. he had a bad connection on a wire n was showing the proper current.. got it all figured out, for future reference for anybody wanting to do a isolator, you dont need the 4th post that is the sense.. only the 3, real simple install, just make sure ya got solid connections

 

There doesn't appear to be any switched line to the alternator. Assuming your battery isolator is installed under the hood somewhere though, you can probably find a switched fuse source in the battery junction box.

I guess I should have refreshed my screen before posting.
