Like I said before thanks, I love learning new things, the way stuff works, just wish I had a play car to do it with and not my main car, but aww well. In the Iraggi instructions, it says its not a good idea to use any type of isolater because then you dont know if the battery goes bad and then it would ruin the alternator, which makes sense. So I ordered the 200A isolater relay from stinger today, and then when they get more in, I will also go ahead and get the battery sensing modules toware it will tell me how the battery is doing.
