In getting our 2018 Tab 320S ready for the season, our left back turn signal and brake light did not work. As the countdown to travel was on and we sought forum advice, we assumed it may need replacing, we ordered a new one, the Kaper II L15-0021 Red LED Trailer Turn Light, from Amazon.
Preparations were made and further tests conducted. Taking the old one apart and checking it for rust and loose wires, it looked as if replacing this may not prove difficult.
While waiting for its arrival, we sought advice from someone we trusted. We took our unit to Sunwest RV Centre here in Courtenay on Vancouver Island, where we purchased this, and spoke with Erik Vierstra, the service warranty advisor. He went over a series of procedures to see if we could isolate the problem. In order, he is what happened:
1. As the tow vehicle lights all worked, he advised tracking the problem from this on back. He tested the brake/light connector. No problem was found.
2. Next, Erik recommended using dielectric grease (as was suggested by ericnliz in 2017) on the brake pins. I purchased a very small tube of this from Lordco Auto Parts and applied this using Q-tips without success.
3. Just prior to travel, the replacement light arrived and there was no time to install this. As a last ditch effort, I decided to give the dielectric grease a final try. This time, I cleaned deeper and much more thoroughly – it worked!
We all lit up and had a great holiday.
Hope this helps others enjoy one too.
Cheers,
Jim
