This is my first post here. I own a Quest 650, which has been awesome, leading me to recently purchase a 2005 Buck EXT for it's bed/utility use. I knew the auto mode did not work when I bought it, but everything else works great. There are no flashing lights or anything, matter of fact the auto light does not even light up when the MAN/AUTO switch is put in auto mode. Could this just be electrical or is this a sensor problem? I have a manual for my Quest but this is a different animal.
