Re: Reverse is not working- Need advice
Same thing happened to my 03, it was suggested that I left the hot wire off the positive battery when I installed the new battery. I checked and it appeared to me that all the wires were connected, it ended up being the reverse controller itself. I was able to find a used one for $ 250.00 and it now works great.
Have your friend check to see that he did not leave the hot wire off the terminal, if it as where it should be my money is on the controller.
This fault is different from the common problem, the bike will move backward a little, then stop. My trouble was the same as your friend, idles up, reverse light flashes but the bike doesn't move at all.
