12V light wiring

8 posts in this topic

Attempting to replace two old style screw in ceiling lights with a RV type & LED bulbs.

After removal of the old poresilin base it was noticed they were wired with house wiring. Two contacts on the back of the base with a "white" lead running to each and one side had a brown on it as well.

There appears to be (2) seperate lines running to this recepticle with a white on each contact and the brown "spliced together" and a single lead comming out of that splice and connected to the one "white" contact on the base ?

The + - is not marked on the base and I'm not sure how this thing is wired up. Is the (white +) and (brown -) ? Cant see why they would "both" be connected on one terminal ?

**note** the house has (2)double receptacles on the outside front. A jumper from the truck battery goes to one, and then there is a jumper outside connecting the two receptacles.

Inside under a bunk lays a jumper cord with + and - connectors. This jumper is (hot) as I plugged in portable 12v accessories to check it, and everything else wired within the house walls (ie switches,hole lights,receptacles,lights) all work through this connection from the outside. I'm wondering if I hook up a (Deep Cycle)inside on the jumper under the bunk if it will power up the entire house and if hooked up to the truck outside if the truck would in turn charge this battery inside seeing the cord is hot when connected to the truck !!

Also, is this type wire "overkill" for 12V and cause of delayed or lost power due to the guage of wire and long runs ?

If anyone understands my mess (lol) help me out with your thoughts.

About the size wire it is overkill it may cause problems with a low battery.

This last week I was helping a friend put in a 240v air compressor. Last summer he wanted to run two sets of wires one for a compressor and another for a welder. The compressor came first, we opened up the breaker box to find that neither one of us labeled the wires coming in blush.gif. The breaker box is on one side of the garage and the outlets are on the opposite side (20ft away) approximately 15ft apart. We could not just use a muli-meter and check for continuity, the leads are way too short. So, I thought that hooking up a jump pack that would be safe enough to check for power. I first tested the jump pack it stated it had 25% of the power, I hooked it up to my 12v light directly and it worked just fine. I then hooked it up to the 10 gauge wire coming from the breaker box, the light should have came on, tested both sets of wires. I also tested it with the multi-meter and I could not get a reading, nothing, from either wire. I then checked the jump pack and now it read 5%, it still lit up the light when connected directly, but, it could not push enough juice through the 10 gauge wire. So, in my experience, the wire you have will cause a delay and require more power.

Granted there was 30 ft of wire the jump pack had to travel, you may not have to go that far in your setup.

and about the wiring for the lights, I know with 12v lights when used in a trouble light it does not matter which power lead goes to + or -. I would think that when the lights are in a series, as long as the light fixtures are wired the same it does not matter which one is the + or -. Someone else chime it and prove or disprove my theory, I am going to try and wire up some 12v lights to see if it does matter this weekend. Bulbs are cheap. I can handle losing some wire, granted it will be a smaller gauge wire that you are using, with any luck it will work without problems, I will be putting in a fuse just in case I run into technical difficulties. grin.gif

If you wire your lights in series and one burns out, they all go out. wink.gif

Polarity won't matter on lights in a 12V system as mentioned.

Well I'm far from a 12v expert at all but thought installing a RV type fixture in replace of the old house bulb style would not be a big deal.

My only issue is why there was a white & brown lead on one terminal together, and just a white on the other terminal of the receptacle base.

Will have to use the marker lights I have to test these leads I guess and try to see whats up. Have a 12v fan I could use where polarity wont be a issue if I mess up trying to figure out the (4) wires in (1) fixture connected as they are ?

This house is used and all prewired with house grade wiring so we're screwed there. Might just have to run new wire in a channel along the base boards or ceiling to the areas we want new LED dome lights instead.

After further inspection it was found both these leads contain (3) wires inside the gray insulator. Black, White & Brown.

One White from each leads to the fixture, both Black are spliced together, and one brown connects with one White on the fixture, the other brown was just snipped off deeper in the insulation.

I connected my 12v fan to the White leads and it fired right up. Depending on which leads dictated the fan "pushing" or "pulling". The wall switch cuts the fan off as it did the light, and the wiring does not get hot.

What the "brown" wires purpose is I have no idea. The amount of "draw" on the fan speed was crazy when I turned on other lights of the old style 12v screw in so I really have a major power loss set up as is.

Plugging in (2) different LED lights of over 50 bulbs each did nothing to the power draw at all with everything else running or on @ the same time. LED is the only way to go IMHO.

Using wire larger than necessary (or just of a larger gauge) will not cause more/excessive battery drain. In fact, thicker wire could, in some instances, marginally reduce battery drain since less power will be wasted as heat due to the lower resistance of larger wire.

Yup. The heavier the wire, the less resistance you will have and like was said there will be less current lost as heat. Small wire with high resistance is why the filament in a light bulb lights up and you know how hot they get.

Well like I said I'm all ears and student when it comes to12V wiring.

The heavy gauge house wire works, just a good delay in lights comming on. Truck running current is right now and strong. Maybe due to the 12' jumper from the car to the house and then 16' house with God knows how much wire behind the walls & ceiling.

The "brown" wire I found connected to the one white was a jumper the previous owner used for connection of the hole lights up in front of the house where this ceiling fixture was.

After getting a new RV dome light installed, I left the brown wire unattatched and of course discovered the front hole lights not working. Reconnected the "brown" wire to the one white hot lead and the hole lights work again along with the new ceiling light and fan installed.

**now I need to get the kid to bring a 12v inside and hook up to his jumpers under the bunk and see if a inside battery will light up the joint.**

It only appears "hot" to those jumpers under the bunk when connected to the truck through the front wall receptacle.

Trying to figure out someone elses set up is always fun when your not real informed yourself !! lol

Appreciate the help here always.. ice_it

      Thanks guys!  We tried kayak fishing last year (around Labor Day I think) and the Rum was way too high.  We launched on CR 7 between Blue and Green lake and just ended up paddling the river.  Is that a good stretch for smallies?

      wow, that is one dark walleye!

      And no reports make forums no good. Participation is what makes this place great.   Do not discourage that!

      Decided to fish Big Detroit saturday with a buddy.  Had bites but my 24 v 75#  trolling motor couldn't keep me in place so that sucked.  When we left the access to go fishing I asked the young man how late they were open till so I could make it back in time to get washed since I was going to fish a different lake on Sunday morning with the nephews.  I will be here till 5:30!  Sounds good see you before 5!  Fishing sucked, Wind BLEW, RAIN SUCKED!  So we packed up at 4:30 drove to access get there around 4:40 and they are gone!  Hot on my heels is a local fishing guide and he wasn't happy also because he had the same game plan.  Was told that there would be one at Melissa till 5 pm religiously.  Got there by 4:55 and they were gone from that lake too.  I honestly don't feel comfortable enough to do a safe job washing since I don't have a pressure washer and I really don't want to spread the Zebra Mussels from lake to lake and I know it was only a few hours 5-6 but honestly whats the point of AIS being there if they don't stay till the house they are supposed to be?  There was an easy half dozen boat trailers still at the access so it wasn't like we were the only two left at the access.

      Had some fun Saturday morning crashing through the lily pads on a small metro lake.  2 fish over 5 lbs and every fish absolutely choked the bait.  All I want to do is throw top water now, haha.  Wish I had longer arms or a partner in the boat for a decent photo.

      I really hope they don't screw this place up. I love it out there and have done a lot of hunting there. I sure wish there were fewer horse trails. It shouldn't be so easy for hunters to access all the woods. That makes it harder to get away from the guys who want to hunt no more than 50 yds from a gravel road.    The dunes seems like a pretty special place to me. DNR does a lot of things that leave is scratching our heads, let's hope they manage this place properly.

      Im staying at Arrowwood July 2-5 and looking to catch some 'eyes for a fish fry or 2. Never been to the area before so I dont have much to go by other than my overall knowledge of Walleye fishing elsewhere. Ill probably be fishing early mornings and dusk for obvious reasons, but also because my boat will be used for the majority of the days for entertaining the girlfriends family. Im open to fishing not only Darling, but Carlos and Le Homme Dieu as well. 

      From what ive read and can see on Google Earth, the lakes are pretty clear, and from experience, usually means tough walleye fishing for this time of year. -I grew up fishing Woman Lake in the Longville/Hackensack area and that lake is as clear as they come. The only way we can snag some 'eyes in the summer is to fish the deep weed lines. Is that the approach I should be taking on these lakes? Does dragging rapalas across mid-lake flats produce? Any help would be greatly appreciated!

      Thanks,

      Gavin.

      Ha, I've read stories about that lake being filthy. And I know about those warnings on the link you posted I just wonder if this stuff is blown out of proportion. Reason being I can't find any confirmed cases of people having mercury poisoning from eating freshwater fish. I know mercury poisoning does exist but can we really get it from fish? You'd think if we could then there would be cases down south where folks are eating catfish from the Mississippi.    We ate a few 30+" Pike during the ice season, I ate more than my wife, and I only did that from lakes that are safer according to DNR and MDH fish tissue surveys. I kept it to once a week for her and I ate the rest. I went over the one meal a week rule several times for myself, but then went a while without taking home fish while the season was closed. I'm not glowing yet haha.    I also don't understand why walleye are always the riskiest fish to eat per those surveys when Pike are above them on the food chain.

      Surely they have a Terrova on the floor. Doesn't matter what size THEY ALL LOOK THE SAME. Also, boat dealers have showrooms with all kinds of stuff mounted on boats.
