Rv Lights Flickering When Plugged In

Disconnect the battery with your rv plugged into a power source.

Rv lights flickering when 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. When i run the furnace after a few minutes the above lights flicker and the above lights and answered by a verified rv mechanic. If not it s the converter.

Most coaches have 12v lights. We could ve used our needle nose pliers to pull out the fuses and see if they were bad. When plugged into shore power at the campground presumably the ac to dc converter will charge the auxiliary battery bank. This went on for about 4 hours and then seemed to settle down and stay at a constant brightness.

When you are plugged into shore power a converter changes the 120 vac to 12 vdc. Sometimes it also charges the 12 v battery and in other cases there is a separate battery charger. If yes it s the pedestal or the connection between pedestal and unit. I have disconnected my negative battery post while plugged into campground service.

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. 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. The battery has water. Recently my lights in my fifth wheel have started getting dim and sometimes flickering.

I am not using the battery to run the camper though i have it plugged into electric. How can i determine whether my problem is a four year old battery or the charger or the converter. So plug shore power back in and have a 120v light plugged into an outlet. 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.

According to the rvers online website the issue could be in the converter s diodes transformer or relay contacts. If the fluctuating did not stop when you turned off the converter unplugged shore power it is on the 12v side of the house.
