I need your expertise, do you believe if I connect the power harness for my famous Humminbird fish finder on my auxilary battery that I am using only for my electric motor that this @*&%$#()*(& fish finder will stop loosing the speed signal or the signal at 25 MPH and above ?? Or it doesn't really matter where the power is connected. Because for the transponder I tried all possible adjustment with no success.<br /><br />Thanks <br /><br />Smoky
