Rv Lights Flickering When Plugged In

The battery has water.

Rv lights flickering when plugged in.

Last trip hooked up to 30amp and lights inside began to flicker my initial thought was that i had too many things on and plugged in so i turned everything off except for one light and it continued to flicker. We could ve used our needle nose pliers to pull out the fuses and see if they were bad. All the lamps fans water pump etc still operate on 12 volts dc just that the dc electricity is provided by the converter instead of the batteries while plugged in. Teriyaki on 09 29 10 07 31pm we were out this weekend and after starting the generator friday evening the 12 volt lights in the th kept flickering.

Seems to be more common when the weather is cooling down and getting a little damp outside i could be imagining this though. Most coaches have 12v lights. Sometimes it also charges the 12 v battery and in other cases there is a separate battery charger. The circuit breakers didn t help the 12v disconnect fuse was in good shape and turning on the rv didn t do much considering all the other rv 12v lights were working.

If the fluctuating did not stop when you turned off the converter unplugged shore power it is on the 12v side of the house. So plug shore power back in and have a 120v light plugged into an outlet. Disconnect the battery with your rv plugged into a power source. If yes it s the pedestal or the connection between pedestal and unit.

Recently my lights in my fifth wheel have started getting dim and sometimes flickering. This went on for about 4 hours and then seemed to settle down and stay at a constant brightness. I am not using the battery to run the camper though i have it plugged into electric. If not it s the converter.

When i run the furnace after a few minutes the above lights flicker and the above lights and answered by a verified rv mechanic. When you are plugged into shore power a converter changes the 120 vac to 12 vdc. If the lights go dim then there is an issue with the converter. I have disconnected my negative battery post while plugged into campground service.

When plugged into shore power at the campground presumably the ac to dc converter will charge the auxiliary battery bank. A quality led will operate on 12 24 vdc some led s are limited to 12 volts dc ac operation landscape lighting and when that type is installed in an rv once the converter charging circuit goes into bulk mode 14 4 vdc or absorption mode 13 6 vdc the 12 volt variety of led is overdriven and will either start to flicker only a couple of the leds in the array or will brighten.
