Reverse not working: FIXED!
I bought my 03 in May, and didn't realize the reverse was not working. Wanted to enjoy the bike through the riding season, so I just started digging into it last week, as the riding season is over.
Symptoms: reverse light comes on steady, but when pushing the starter button, reverse would engage for 1 second, the rear wheel moved about 1", and something loud could be heard tripping off, reverse would stop immediately, and reverse light would go out. To try again, it was necessary to turn off the reverse switch.
After pushing the reverse switch on again, I could hear repeated, fast ticking coming from the relays' box. Specifically, if I touched the RVS relay (fourth from the left in the bottom row of relays), I could feel it clicking, which told me that the relay's coil was not getting good 12V voltage for the contacts to stay closed.
One side of the coil goes to the reverse regulator module, and the other goes to the reverse control module. So, I figure the problem could be at either end.
The reverse regulator is accessed by removing the left saddlebag, and it's located just under the top frame member on the left side of the rear fender. You don't have to completely remove the saddlebag, it's enough to remove the 4 screws holding it in place, and wiggling it out bottom first, just about 2" from the frame. first it is necessary to remove the rear center plastic piece between the two saddlebags (where the license plate is located).
After carefully removing the regulator from its rubber mount, and unplugging it (connector wiring and module really badly covered with 11 years of road dirt), I found that the 2 pins at one end of the regulator connector were badly corroded (covered with a green substance). I carefully cleaned the tiny pins with a sharp blade, being careful not to bend them, and pushed a bunch of dielectric grease into the female connector end. Plugged it back in, and tested the reverse again: it worked!!!
Just thought someone might benefit from knowing what I found to be the problem.!
