Mr Dastardly, just get yourself to the Lakes dooooo and we'll have a look. I will be bringing my bike in the back of my Transit so we can swop the switch over to check............... and if you really need your grips heated you can have my switch and I can get another ............whenever!
(PS I've got Symtec as well, they are not the hottest and can take some time to heat up.)
See ya there.
