Electric windscreen - relay?

My electric windscreen gave up!
This week i installed an Aeroflow windscreen (replacing stock version) but now after 2 days, the electic up/down switch doesn't do anthing anymore and doesn't produce any sounds either. Completely dead!

I checked the fuses but they seem to be ok (the windscreen is in the same group as the horn, which is still fine).
So now i assume there must be a relay issue of some sort?

Can anybody help me out here and provide a few good pointers please?
Would like to avoid having to spend another 100+ euro's at the dealer...

Ronald.

Relays are easy to test, provided you understand how they work. Is the windscreen relay similar to the standard Bosch units for the lights and load-shed? If so, unplug the relay. Relays have a control side and a controlled side. The control side (small load) kicks the relay over to run the controlled side (big load). Put your circuit tester on the control side first and hit the switch. If it lights up, then you know the control side is working. If it doesn't, you're open either before or after the relay. Run the positive to ground and if it lights up then it's after the relay. Now, plug the relay back in and hit the switch. The relay should click. If it doesn't, then you know it's a bad relay. If it does, check the leads on the controlled side. If your getting no continuity, then your relay is bad or you have a bad connection somewhere before the relay. If you have power at the relay and after but no joy at the windscreen, then you're open somewhere between the relay and screen. If it's not a standard Bosch relay, the same as above applies but you'll have to determine which lead does what as far as the control/controlled side. Hope this helps!

Thanks, very helpful and will come in handy.

Now... is there anybody that can point me to the relay for the windscreen? Where is this located on the bike? Is it easy to reach?

thanks
