    It is possible you have wired the LED LAMP wrong. The LEDs will not operate if the wiring is not correct. The polarity may be reversed. Swap the two wires feeding the LED lamp and try again...

    On mine, the white wire is positive and the black is negative. It looks to be the original wiring and does not have a fuse.

    That sounds wrong and could be your problem. Trace the wires from the battery to the converter. If you come across a connection to the frame, that wire is negative. Otherwise, at the converter, you should be able to determine which is positive and which is negative. The standard is that white is negative. I had a similar problem with my old Bonair. The previous owner had wired the battery backwards.

    The standards are for RV's is BLACK is POSITIVE and WHITE is Frame Ground from the manufacturer.

    In the Automotive world RED is POSITIVE and BLACK is frame ground from the manufacturer..

    You might want to hand trace that out and make sure the BATTERY marked POS or (+) stamped symbol on the battery case s using a BLACK colored cable and the stamped symbol (-) or word NEG is using the WHITE Color cables. If this is not the case them you may have the battery cables reversed.

    Looking at your BATTERY photo I think I see the BLACK cable is going to the LARGE BATTERY Adapter Post and the WHITE cable is going to the smaller Adapter POST. This is not the correct way to install the battery cables... However they may have been changed by the previous user to look like the AUTOMOTIVE WORLD standard wiring so you need to go look at the 12V DC Distribution Panel and the DC OUTPUT cables from the DC converter and see where the colors are being used...

    I am looking for the 12VDC Power Distribution GROUND cable going to the trailer frame ground is using a WHITE color cable. I also may not be seeing the two BATTERY TERMINAL ADAPTERS as different pole sizes. They may be the same size so find out what is stamped into the battery case to be sure. WHITE should go the (=) POLE terminal and BLACK should go to the (+) POLE terminal...

    I am basing this on what 'I THINK I' I see in your battery photo and cables. Don't change anything until you hand trace out things first...

    Maybe others on here can explain it better. If I am totally out in left field here please disregard. This could describe your posted LED problems being wired wrong polarity too...

    I did not install new lights in the camper, just new 1156 LED bulbs on the ceiling lights and the outside light.

    If i had the wires reversed, would the lights and water pump work? I will check to see if I can find the wire that goes to ground, but all the wiring is inside the frame and is very hard to see.

    I feel stupid but here is an update. changed battery wiring around so white is on the negative and black on the positive and now the led light bulbs i had installed now work. I must have reversed these wires when i installed the battery in the spring and have never needed the battery this summer as we always had power. It is just strange that the water pump and other lights worked with the wires reversed. Thanks everyone for all your help.

    WOO HOO....

    Glad to help you catch it... Things sure get weird sometimes... The automotive type DC light bulbs don't care what the polarity is. The water pump may have been working in reverse ??? Motors will do that if the polarity. I jumped my tongue jack one time and got the jumper cables reversed. Down was UP and UP was down but it still worked hehe...

    Now I'm curious why you didn't have blown REVERSE POLARITY fuses... Who knows what the folks do with the older trailers before you get a hold of one...


    Glad you back on good grounds now.... I marked my HOT +12V battery cables with RED FINGERNAIL polish. Alot of folks use their cell phones to take a picture of things and they are always available to them to scroll the camera back and view them when needed...

    Bet you are somewhat relieved now - got sit down and have a brewski hehe...

    All of us are allowed one goof up... Just one however... Being involved for many years tent camping and having my off-road popup camper since 2008 I sure have made a few blunders... The ones I really remember was when I 40 -50 miles back in the woods some with no WALMART or LOWES close by...

    Now i work really hard for having a GOOD PLAN B on everything that can happen...

    I think I passed one Goof up about 15 trips ago. I'm on to Goof number 20 at least. (I Forgot to stow the Gray water can when the Popup was open, ended up in the back of my SUV for the ride home)

    yes, the lights would work and the water pump would spin the wrong way!

    if you 6620 has option C it charges the battery some and could explain the drop in voltage from 12.4 to 11.8!!!!!

    I believe the Colemans came with a circuit breaker mounted to the frame near the battery, do you see a small box spliced into the positive wire?

    No, not on C/F campers, they use use a self resetting(also known as a short stop) circuit breaker of 15A to 40A on the battery pigtail depending on the model. Looks like a goldish color box on the black wire positive wire.

    Done that, now I don't remove the wires from the battery just disconnect the pigtail at the connector.
