Analog will definitely pick up more than a digital but will still miss many events that will make the led flicker... They're faster but still slow... A large but short dip will look like a tiny fluctuation... If nothing more reasonable works you might need to borrow agood oscilloscope to really see it... Old burglar alarm installers might still have a device they used to detect short breaks in the foil they lined windows withUse an analog meter as digitals can be slow reacting to changes
Are they parallel connected, series connected? If so are the three bad lights near the end of the wiring run and the two good ones at the beginning? Maybe bad/loose connection somewhere in the string?I just started following this thread as my cabin lights are LED and have been for quite some time now. I went to the Phillipines for 6 months and was off the boat. I had friends checking on it as we had quite a bit of rain here in Calif. Upon my return I fired up the cabin lights and some of them flickered a bit or were dim. Then they went off completely. I have 5 cabin lights and only 3 were affected. Then all of sudden they all started working fine and then a few minutes later 3 of them went off completely. I checked the bulbs in the other working fixtures and they were good. All connections behind the dome fixtures look fine. Not sure where to start... Any ideas???
Yes I would think so as well. It would be hard to say though until the wiring for all the lights was examined from beginning to end to confirm how it was wired. If wired in parallel, its possible for the three flickering lights to be at the beginning of the string if they are all on the same wiring run. Another possibility is just a weak battery bank. This would be easy to confirm just by charging it full and while full and the charger is on, do they still flicker?I wondered about that, but I don't know how to test that. Really strange. I wonder if they are in series, but the ones that work I would think are at the beginning. Hmm Thanks let me play with this.
