12 volt lights

hello, I am new to the forums and a new (used) 2006 shamrock.
Was tinkering with the idea of putting in a 12 volt charger for my stinger flashlight. We have only used the camper once, and always had hydro. I also noted that there wasn't any cigarette type plugs for which I thought I could use for this particular charger. My thinking was to tap one of the 12 volt lines to put in a small manifold cigarette lighters to charge car adapter items. After a closer look it seems that even though there are 12 volt lights throughout, there is not a switch and or option to operate them with the onboard battery. I can still tap into the 12 volt lights, for the charger (or just keep the plug for reg hydro), but was surprised to see that there was no lights available whilst on battery only. I just wanted to confirm that this battery, I guess would only be used for the emergency brake dissconnect while towing.
Not so much of a big deal as I can use a regular outlet and just purchase a dc converter for the light, but I was surprised to see that.

Hello, and welcome. I'll take a stab at this, can't know for sure without a few more details. Somewhere you should have a converter, that recharges the battery and operates the 12 volt stuff while plugged in. Most have a brown slotted cover that will also provide access to the breakers and fuses. Mine had a empty fuse holder, so I added a 12 volt cigarette lighter socket and ran the wire to the empty fuse holder, and added a fuse of course. We use ours for an electric cooler.

If you inspect far enough, I think you will find that not only the lights, but also the furnace fan and water pump use 12 volt, and the refer and hot water water must have 12 volt to light. Should have several auto style (ATC) blade type fuses.

Good luck, and hope this helps.

thanks

thanks for the quick reply. all is exactly as you described, (brown slotted cover, breakers on one side, auto type fuses on the other.
and my thinking was exactly like you said, I would have thought that when the camper was unplugged you would need the battery for such things as you described, but is there a seperate switch to enable lights? when mine is unplugged nothing works, (water pump etc) I assume the hot water tank still uses the 12 volt to ignite to gas when switched to that, but have not tried it.
sorry for being a little dumb with this, but I did not receive any manuals with my shamrock when i purchase it.

The lights, the fridge and hot water heater igniter, water pump and furnace should all work off of the battery when not plugged into electric. Start with a volt meter at the battery while not plugged into 110 volts, and see if you have power there. It is possible that you either have a disconnect switch or maybe a hidden circuit breaker if the battery checks out good.

feel real dumb about this now.............I probably have a dead battery.........and would be willing to bet on it as the camper had not been used more than two years before i bought it. Will check that straight away, and get back to you with results...........thanks again for quick replys.

checked battery

well after checking battery with meter......shows 11.8volts.

car and truck show 12.4+.

with trailer plugged in on battery level indicator shows full.

unplugged there is nothing on lights at all (would it not even show a dim light with a battery that is low?)

I cannot find any switches on or near breaker panel or battery. So am stumped again.

11.8 volts should be plenty to work all of your 12 volt appliances.

On many trailers (including mine) there is a circuit breaker (or fuse) on the hot wire near the trailer tongue. I think most automatically reset, but it is possible that has not happened if you have such an item. If you have a covered bottom, you might have to pull that down some to find that puppy......I have to pull my bottom down to get to mine (am I allowed to say that?? ).

Check for voltage going into and coming out of that.

hmm.......just checked and I dont see any fuse or circuit breaker......there is a small control box leading to cable for emergency brake activation (i believe) and there is an inline fuse to the electric jack.......its fine, and further back under the trailer there is a covered junction box (which i havent uncovered yet)

Nothing that looks like post #2 in this thread: 2010 Rockwood 2604

You might have to pull the cover off of that junction box next, or pull the converter out to see if you have power going into the back of that. I don't think there is a master fuse for 12 volts on the power panel, but I can't remember.
