Getting my heated gear out and ready for a ride. I have Warm n Safe gear with a heated jacket liner. I'm using the remote heat troller. No LED light and no heat. Check the power from the battery. But the instruction say to replace the little watch battery. And they say to remove the screw and remove the lid. Well, so far I'm not sure which part they're talking about. I have'nt found anything with a lid. Where's the little CR2032 battery at??
