Heated Grips Not Working

[clowrie]

Coldest day for a couple of weeks and my grips decided today was a good day to stop working. I washed bike at the weekend, but with sponge and not jet wash so don't think I would have knocked anything.

Anyone any ideas on common faults with these - and how to fix!

Mine's a 2010 R1200 GS

Thanks for any help
