Dont quote me, like I said I'm sure someone will be along to tell you different. I guess it could have just been a really hot day, and to much stick... the light is to warn you that you 'could' be doing damage, so all might be ok. Like I said reset the error code and see if it comes back on I guess. Then again, maybe I should stick to being a sparkie, tried to be a chippy today and thay almost ended in disaster! Felix
