Hi friends, I have a 2017 Tab 320 S. I noticed while doing a pre-trip walkaround this past weekend that the right tail light wasn't working. I got my screwdriver and voltmeter out, unscrewed the right tail light out to see what was behind it and before I did anything the left tail light stopped working too.
I took a closer look and the left tail light was actually still turning on, but quite dim. This made me suspect an issue with the connection to the TV so I unplugged the pigtail and checked all 7 pins on TV side with the voltmeter and they all seem to be working fine.
I plugged the pigtail back in and measured the voltage at the trailer battery with the TV turned on and only measured 12.9V. The pins on the TV were putting out something like 13.6.
A short while later, both taillights magically started working perfectly again. I checked the voltage at the battery and now it was 13.6 as expected.
So my theory is that the pigtail is bad and I should throw it out and get a new one. I'm not able to reproduce the issue anymore though so I can't be sure that's actually the problem :(
Has this happened to anyone else? Am I on the right track? Is it easy to replace the pigtail?
