Do you google everything? I've installed these things. a .7v drop would make it very difficult to charge a battery since most oem alternators dont run at 14v all the time. I dont even need to look at that link bcause I know what im talking about.


The only time you will see a .7v drop is with a really crappy isolator or a really crappy wiring job.


Why dont you take a multimeter to Toby's shop and check his SUV.. I think he has one in there.
