Some mentioned the reverse relay in the electronics box. I checked Clymer and cannot find a "reverse" relay (Clymer p307-308). Could it be the Load relief relay (shown on the schematic, Clymer p 612)? For that matter, is there a way to check if the relay is working?
Final step will be to check the speed sensor (Clymer p. 318). That is $152. Again, does anyone know of a way to see if this is working or not?
Wow, this stuff gets expensive after a while. I hate just replacing everything by trial and error. Maybe I will follow ibbones example and just ride w/o a reverse!
THANKS AGAIN to everybody for your help!
sorry to hear about your persistent reverser problem. I reply to your PM public as others might find it useful as well...
My experience of the reverser problems is limited to the more common symptoms: reverse working but then stopping after few seconds.
I was able to watch my technician at the dealership working on this issue back in 2005 (bike was under warranty). Now looking back he was using a trial / erroe method rather than really having any big experience on the issue.
Anyway, he started by going into the main electronics box under the gas tank. There is a relay (which I personally don't know what it is for exactly) that he changed since "he had once done it to another bike". This did not help.
As the second trial he changed the big control unit. This did not help either.
As this was my second visit to dealer because of the same problem we agreed that the third attempt will be done by myself. (I had already learned from this forum about the speed sensor.) So he gave me one as we agreed that I will change it myself during my winter projects. And this solved it.
Of course trying to solve the problem by trial and error is easy to do when the bike is under warranty. The technician can just order any parts he wishes and he even gets paid for his work by the factory...
I wonder if you have seen the posts on the reverser problems on the old LT site. For instance David Mack (aka beemerlt) wrote an extensive summary on the various reverser issues: (unfortunately the pictures have vanished somewhere...)
Ar far as checking a multi pin relay functioning you would probably need a diagram of the internal connections of the relay in order to be able to check it with a multimeter. I'm not much more of an electrician unfortunately...
