I have a WAC low-voltage monorail (probably a SOLORAIL model) that is about 7 years old. The rail is about 12 ft long and has four fixtures attached.
For the past 2 years, one of the fixtures has shown an intermittent connection. It will turn on full brightness and work fine for 10 mins then "flicker" and go out. Sometimes it doesn't even turn on. If I wiggle the fixture, it will stay on for a while then turn off.
The fixture is a Quick Connect QF-195x2 with platinum finish. It attaches to the monorail using a Quick Connect Adapter (LM-QADP).
I've disassembled the connector and fixture as much as possible, tried to clean a spot that looked corroded, and tried to make sure no shorts are happening (e.g. there is a plastic washer in one spot to prevent a short contact). After I've rebuilt the connector, it will usually work well for a few weeks then start acting flaky again.
Is there a definitive way to repair this fixture or should I spend approximately $70 to buy a replacement?
