DC Relay

Today, I moved my 2019 Montana 3720RL about 40 miles to a different campground. When I got here I exercised my Onan 5500watt generator for about an hour. After shutting the generator down and back on 50 amp shore power, I noticed the LED lights flickering about every 10 seconds or so. Investigated further and heard what sounded like a relay clicking in time with the lights flickering. The sound seems to be coming from behind the basement panel on the the front side of the basement. It seems to be affecting the auto-leveling control too. All the lights on it light up momentarily in time with the clicking. AC power seems to be working fine.

Anyone ever have anything like this happen to you. And what was the cause/fix?

Sounds like your transfer switch is sticking. There have been a batch of bad ones. You can try tapping on the unit or taking all power off then turning it back on. Your ATS may need to be replaced.
