I may need to access the battery and in order to do this I need to remove the "Rear Side Panel". I have read the instructions from the owners manual, but I do not have the tool to remove the two "Silver Screws" attaching it to the "Top Side Panel" ( The tool did not come with the tool Kit). Also do I need to take off the "Top Side Panel" completely in order to remove the "Rear Side Panel". I have a heated Corbin seat and left it on. It ran the battery completely down and I am having trouble Jump Starting the bike. Do I need to put the battery on a charger or do I need to replace the battery. Thanks
