Thanks very much for the replies and generous offer! I think it is the battery and I am going to see if I can find a replacement , I am not getting power at all so I am sure that is it. Thanks again!
I was hoping Someone could recommend a good reliable Combustible Gas Detector that won't break the bank. The one I have been using (a Tif 8800 donated to Me by a Friend), stopped working. Thanks for any input!
