Accidently left multimeter at homeowners home in the attic from last job Homeowner let me in and I went up to get my tool Asked if system was still cutting on and off and he stated that he has had to mess with it a few times I went ahead and took panel to blower and control board off so that door would not put pressure on wires to cut it off Leaned panel up against so debris would not fly in System left with power upon departure. Thanked homeowner for allowing me to retrieve my tool
