Trying to install a winch on my "one ride old" Honda. Having trouble getting the top bolt out of the battery cover due to a terrible design. The bolt has a "washer" style nut that has plastic that is supposed to hold it captive. I put my 10mm wrench on it and it broke out the captive plastic (with very little effort) and none of the pliers I own are capable of holding the washer nut to get the bolt out while the box is attached to the vehicle. I am curious if anyone has removed the battery box? I can't get some of the plugs from the harness's to come out which is more frustrating than the issue that caused this whole mess. Being unable to remove the battery box is leading to a vicious circle that makes me want to have a $9000 bonfire. Any help or ideas are greatly appreciated.
