Heat link has no power

[Joann3]

Hi …

everything has been working fine, i went on holiday and returned to low battery on my nest. I have used a few troubleshoots and  have tired to reset by pushing the reset button for 20 seconds but there is no light (green/yellow) 

I have checked all wires and connections and all is fine. The heat link is just dead.
