flickering house lights

What we need now is additional info from the OP

AS pusherpilot mentioned in his reply, it may be the 12 volt cut off relay aka salesman switch that is causing the lights to flicker. A quick and easy test to determine if the cutoff relay is the problem is to place a jumper between the two large red wires attached to the relay and see if the lights stop flic
Good Luck Don

Wonder if a bad/poor quality converter can cause a 60 HZ ripple in its 12 VDC output?

Easy to tell-- disconnect from shore power/generator and see if it changes.

My first thought also but as Bob posted you can't see a 60 Hz flicker. Now if the coach has LEDs that changes everything.

You wouldn't see 60Hz. Maybe a harmonic subset, like maybe 20 Hz, but not 60. The eyes / brain don't process that fast. Just sayin'

Still could be the converter . . . . .

My daughter's pop-up flickered with 12V LED lamps. This was on shore power and I don't remember if she had a battery in her pop-up. The converter may have been part of the problem.

Didn't have time to play with it. We simply put incandescent lamps back in.

If the OP has LEDs he might try and incandescent in a lamp or two.

Ok let the arguments begin. Will you define flickering, one could mean dimming as flickering. Jeff an incandescent light bulb certainly can appear to flicker as you say. In my 40 years as an electrical contractor, I've seen many different situations that could be considered flickering. An inductive load starting can makes bulbs appear to flicker, bad connections, In this case I thing the OP should isolate the converter charger first

When he describes and compares a flicker to a florescent, thats pretty specific. He said "like a florescent", not that it is one. And we both know incandescent simply cannot flicker at 60Hz

Incandescent lamps cannot flicker like a florescent simply because they cannot switch on and off that fast. Are these LED's you are talking about? THEY certainly CAN flicker that fast.

Either way I would check the battery and see if it's disconnected, or electrically open.

Thats the standard response for electrical issues, Bad Ground. I assume your lights are 12 volt. I think maybe the issue might be in the converter charger. All the lights or a few?

Agreed.

If you ensure your batteries are fully charged, then disconnect from shore power, do the lights still flicker?
