Customer called us out because switch in master closet was stuck on. Once i arrived I took a look at the switch and discovered that something inside was broken and it needed to be replaced. After I preformed my inspection i found the following issues. Old challenger panel with corrosion on main lug and box itself, multiple two prong receptacles with no ground, very old switches from 1938 along with a rusty meter can and service cable straps. I recommended we replace panel and meter can along with swap out the older switches and plugs. I fixed the broken switch today but will need to return to replace the other switches and plugs. Customer has canceled us coming back to replace the other devices that need replaced. I have edited the ticket for the one device replacement.
