New wiring harnesses fixed the errors but now the speedo doesn't work which the dealer is blaming on the Rostra CC.
The dealer offered to uninstall the CC for 2h of shop labor @ $89/hr. After that if the speedo doesn't work all other work will be covered.
What do you guys think?
The bike has been in the shop for two months.
The problem with that is if they remove the Rostra and the speedo still doesn't work then they can fix the real problem and still charge you for removing the Rostra. Hmmm...what to do. They sort of have you by the short hairs here. Do you think they could leave it all in place and just disconnect it "electrically" from the bike so that if it doesn't correct the speedo problem then you or they could reconnect it? The only thing that I can see between the speedo and the Rostra is the connection to the speed sensor and I think the bike would throw a code if that wasn't working. Do you know if the speedo does it's swing the needle thing when it's first turned on? I'm not sure where your Rostra is tied into the speed sensor, but the sensor wire goes both to the ECU and the instrument module, if the speedo isn't working but the ECU is not giving a code then I would suspect the connection between the sensor and the speedo rather than the Rostra.
Maybe the dealer can "fix" the Rostra as he originally offered (first post this thread) to do at your cost and fix the speedo under warranty when that doesn't fix the problem? You might want to offer Brian's instructions and maybe even Fred's wiring diagram if you decide to go that way. We all know those work. Not knowing your dealer or the wiring prowess of the PO makes this difficult to help with.
It is potential problems like this that gave me pause when I installed my Rostra. I was lucky I guess, both with my install and my dealer. Best wishes, please keep us informed as you have been doing.
