I have the true amalgamated dual battery kit on my 16. I was wondering where other guys grounded the second battery to? Did you go battery to battery on negative or ground to the frame?
I was afraid you would say that. I have mine tore apart right now adding a winch stereo and a damn light bar lol. The money just doesn’t end with these things does it lolTo run more accessories...........light bars, stereo, winch.......etc. without killing your main starting battery.
