Bonneville SE Speedo not working

I recently changed the front wheel on my 2009 Bonneville SE, due to the original wheel having a pinhole and leaking air. I got a used wheel off ebay and this is holding air, but now the speedo won't work.
I'm guessing I've put something back the wrong way round, but what ? Any ideas ?

Haven't had chance to have a look yet, but hopefully get it in my mates workshop on Monday.

 

Thanks thebiglad, here's some photo's... http://i67.tinypic.com/2igewcg.jpg

All seems connected properly at the speedo head.

 

Looking at the pics I'm thinking maybe I didn't get the two tabs from the speedo drive washer into the drive. Looks like the speedo drive only goes half way along the stop on the forks.. If that makes sense ?

 

Thanks thebiglad. I've come to that conclusion myself. I hope to get it sorted tomorrow. Will keep you posted.

 

Well, I got it sorted today. I'm almost ashamed to admit what the problem was
At least you can have a good laugh at my expense..

Took the wheel off and there was no speedo drive washer. In our haste to get the wheel on, we never even noticed..lol
Took the washer out of the old wheel and into the new one, re assembled it and hey presto, one working speedo.

Thanks to everyone who offered suggestions, they are all much appreciated..

 

Like you say, the main thing is it's sorted..It's good to have a laugh as well.
