I accidentally drilled into the control-unit wires of my old Sears garage-door opener. There was a tiny electric spark and a slight smell of ozone. I repaired the wires, but the unit does not work (no light, doesn't open or make any noise). I THINK it did work prior to my mistake although I am not 100% positive as it hasn't been opened in years. The electric-outlet it is plugged into works fine, so it is getting power. I did not see a fuse inside the unit, nor any obviously-burned parts. It is c.1974, though it has been used VERY little. I have no specs for it. It is a "Sears Best", 1/2 horsepower, chain-drive. I have little experience with electric motors, so am not sure what to test for or where (e.g. with a volt-meter). Suggestions welcomed! Thanks.
