At first I thought that this was broken as the light only worked for a couple of seconds. I have two systems, a 2001 and 3001. This works for both of them. Just be sure that you place this in the charge port all the way in. I guess I didn't push it in far enough in the beginning (I didn't want to break it or cause damage), It was kind of loose. The second time around it started to work just fine. I've only had mine for a week so I can not comment on how long it will continue to work (weeks, Months,Years, ect.), But so far so good.
