Most likely the electrical pins in the connector from the microswitch to the harness is rusted and now don't have a good contact. That was what was wrong with my X when I purchase it. I just spliced the wires together and it been fine for the last two years.

You will need to hook an ammeter in series with the battery and observe the ammeter to determine if you have a parasitic draw. The X should go into sleep mode and the draw should be very little after 30 minutes. If the draw is still high, the X is not going to sleep mode. There has been a lot of thread on this issue. Just do a search.

If you don't know how to connect an ammeter in series with the battery, there are several videos on Youtube.
