@ai6yr Yep. Had the same problem at the restaurant. When I got to it, various Mickey Mouse repairs had been made by others. Plus halogen bulbs, hot transformers, bleah. But we're now in the era of LEDS so I ripped it all out and replaced it. Been running for years now and people don't even remember what a constant hassle was. But I remember.
@shuttersparks Rather annoying to have proprietary stuff from the 1980's or 1990's (no way to add lights!). I'll probably pony up the $$$ and do it while the family is out of the house, LOL.
