Thank you for your response (sorry so delayed). The alternator was replaced and the battery checked out okay. The lift has the cut-off switch next to the seat. Not sure if it matters but it's the type designed to be used in a place where fumes and vapors could be present. "No spark" or concealed spark. I am using your advice on pulling the fuse one by one. The problem is I located 2 more stray wires that were cut (not sure on purpose or not). Could there be a generic schematic for basic/standard electric systems?
