Just wondering what my steps would be in diagnosing a non-working speedo on my 2017 Expedition with a 600 ace. Don't want to just start pulling stuff apart. I've not had this sled disassembled and am not a seasoned sledder so any additional info/steps to take would be appreciated.
Just wondering what all I need to check and the order of which is most likely to be the issue.
Any other information needed for you guys, please ask and I'll fill you in. Thanks ahead of time!
