I did as you suggested, and sure enough things were not connected inside the plug, but....
(sorry about the size of the photos. I resized them in Photobucket, but it isn't recognizing the change)
after shaving off some of the plastic, I reinserted the wire and tightened the screw on the wires.
.... but when I plugged the tender in to the accessory socket and then in to the electrical outlet, I am still getting a blinking red light instead of a soild red. The charger says that a blinking red light means the battery is not connected. A solid red means it is charging.
I am guessing my next step is to check the auxiliary socket fuse. Is that correct? All I could find was this diagram:
but is says it is for the 1100GS. Is it the same for the r1150r?
Also - I am assuming it is fuse #3 which according to the key, means it is always hot. So, now I need to know if I am heading in the right direction and how do I check a fuse that is always hot? Can I pull it without disconnecting the battery? Cuz - if I have to disconnect the battery, then well, I'm going to have to do more research to figure that out.
