Hi all- Can anyone offer any insight into a problem I've noticed for years but don't know how to solve? I'm a self taught neon tube bender. I am not an electrician or electrical engineer. Through the years, I've noticed neon tube, fluorescent lamp, transformer and ballast failure more often at restaurants than other places, in downtown areas in cities as opposed to smaller suburban locations and where the city provides the power. Guys on a sign repair truck do basic voltage tests but not much more. They aren't really trained (around here anyway) in anything more technical. When I bring up the subject, most companies I deal with are more concerned with getting the job done and getting paid. What can I look for besides voltage spikes, sags etc.? Who would have the proper testing equipment. Thanks!
