[AT] engine heater

[john hall]

As a few others have mentioned, check also your drop cord and the outlet. I 
went to get a tractor one day that had been plugged up for a few hours. The 
cord was burning up where it plugged into the heater. I now use an extremely 
heavy drop cord that is very short in length.
