CLock/Speedo unit not working

[Chilli]

2005 250EC

My clock does not want to come on. I have tried another one but alas, same thing. I have therefore eliminated that issue. It seems as if it is just not getting power. I have checked connections and seem in tact. Checked against the wiring diagram and seems to be connected correctly. There is power in the system as the light and hooter work, but not the damned clock
I have absolutely no bloody idea about electrical and wiring.

Any grand ideas? Please not too technical though

Is there a battery in the back of the speedo unit?
The older round style speedos used an "N" type battery I believe.
The newer rectangle shaped ones use a 9V.
Check to be sure, that may be your problem.

Thanks a lot. How easy was that not !!!!
Battery in and clock working. Now that was the type of easy solution I was looking for

As for GG user manual
Well, I dont think its worth the paper its printed on. It doesn't even let you know there is a battery. I have also come across other serious short comings in there. This besides all the Spanish words thrown in here and there and some lovely spelling mistakes just for good measure.

Where exactly is the battery?

Remove the clock, turn it up side down. There you will see 2 screws. Its under that cover

Here are 2 pics of my speedo.
First one is altogether.

This is it with the back off.

Where is the battery exactly?
