f1100turbo-To be honest, I'm not sure. It's been a long time since it was running on something other than 110. I have noticed a dimming/brightening of lights when I'm leveling, now that I think of it. The motor is running at that point, of course. I don't know enough about the elctrical system of my coach to know if these symptoms are related.
In reality your lights should never really go bright or dim when hooked to shore power.
Also check this.....
Whith unit plugged into shore power turn on as many lights as possible and then go to your power center where your converter is located, you should hear a fan running with all the lights on.
You should also see 13.7 plus volts at the battery/batteries.
"Normally" when lights go dim and then go brite forr awhile then dim again your converter fan has stopped working and your converter is over heating.
When it overheats the converter shuts down "dim lights" then after it cools it comes back on "bright lights"
