r/Wiring

Hey redditors,

Can you tell me what I’m doing wrong?

I’m installing some led lights in my bathroom and basically I was splitting one of the ceiling lights to run a cable that connects to the power supply, then the smart controller and to the led strip.

From what I’ve read, the controller can’t connect directly to the mains and it needs a power supply to convert the power from the mains to the led strips.

I’ve connected everything using the power supply and seems like no power goes through. However when I connect the controller directly, *some* power goes through but seemingly not enough to power the leds.

I’m completely at a loss here and desperate for some help

This is the plug to a windows AC unit and I have no clue how to go about plugging it in without a converter and idk what i would even search up to find one. (Idk if this really matters but im in the US)

Hey howdy! Figured I’d try this because I can figure out most things on my own but I definitely need some tips here. I bought this camper topper from China lol so you know I have no instructions. Anyways, there’s a third brake light and two accessory lights on the upper right and left sides (they’re amber I think so maybe blinkers). Anyways, the two lights on the sides, have a red and black wire for each, but the third brake light in the middle has a red black and a white wire. Is this maybe a backup light too? Anyways, obviously I want the brake light to work when I press the brakes only and I want the accessory lights to go with my blinkers maybe? Luckily it came with the wire extensions as shown. I have no idea what wires to tap into though to get this to work. All I know is that I’m pretty sure I’m supposed to tap into one of the rear tail lights.

I have a 24V battery for my daughter's two-seater G63 ride-on SUV, and I need to replace the battery wiring harness.

The original harness has a 17A resettable circuit breaker, but I can't find a replacement anywhere. From what I've been able to learn, replacing it with a 20A breaker seems like the closest and safest option. I also found 30A and 35A harnesses, but those seem like they're rated too high for the original wiring and controller.

Does anyone know:

• Where I can buy a replacement harness with a 20A breaker?
• Or where I can find a 17A replacement if they're still available?

I've searched Amazon, eBay, Monster Scooter Parts, and Google without much luck.

Any recommendations or links would be greatly appreciated. Thanks!

I'm not a handy person but the light switch in my son's bedroom needed to be replaced. I watched a couple of youtube videos and it seemed reasonably straightforward. I went to home depot and bought a new light switch that had the push and click style for the wires.

When I opened the box and pulled out the old switch I saw two black wires screwed to one terminal and no wires screwed to the ground. I did notice one bare wire screwed against the box all the way at the back.

I'm not sure what to do now?

I pulled the board out of my Bose acoustimass 5 series 2 to remove the vinyl wrap that was tearing. The way Bose made these connections doesn't seem the greatest and isn't really possible to redo once its time to reassemble. Any recommendations on terminal blocks or connectors. I can solder, but i only have basic tools.

do I put both ends of the same colour in the yellow circled thing? and secure it with the clamp that your screw on?

We’re just at a loss after trying to figure this out all day and what to actually connect, any help would be appreciated. Our basement light went out after a decade. New bulbs didn’t work so we decided to do the ballast bypass.

It’s a dual 8’ Single pin light with Type B Ballast Bypass bulbs we got. I’ve cut the four wires that connected to the ballast and stripped them by 1/2 inch. I just don’t know what to connect to anything, it’s not clear with any research. AI has not been helpful as well.

One side - One white wire coming from the tombstone is capped or connected together with the white wire coming from the yellow power supply. The same for black. The other white and black wires coming from the tombstones were connected to the ballast.

Other side- one red and one blue wire. That end pushes in like a spring to remove the bulbs.

I added a picture of instructions of what came with the lights themselves if it’ll help

I took realme buds wireless 3 as their left side wire got faulty so I directly joined the kz wire inside battery compartment without soldering and superglued it but the right one has boarded in inside and I don't have soldering iron to directly join the wires, I want it looks like oem product rather than diy project so I could also use it in college

From the plug wire I got a lil copper for sure but I'm unsure if this other wire is also copper or if it's a different alloy?

My house is from the early 1900's and has mostly plaster+lath walls. I'd like to do some runs of ethernet cable between floors of the house, but every approach I take seems to end up hitting a hard stop inside the wall. Dropping wire between studs from the attic? Hard stop about 5 feet down. Dropping wire through a hole in the wall on the second floor, trying to reach the first floor? Theres a horizontal barrier of (what looks like) right above where the floor joists should be (see pic looking down into the wall--there's existing wire that dives straight into a pile of rocks).

How in the world do I actually get cables through this mess without destroying the house?

trying to do some wiring for a light, would i be able to solder on a connector coming off the wire on the battery to connect to the light and then leave on the connector that comes with the battery for charging? I also have a switch that’s going in between the battery and light. battery is 12 V and so is the light. obviously id disconnect the connector going to the light and stuff before charging. I have all the basics like soldering iron and all the cables but just need to know if this is gonna explode or not lol

I bought this LED strip light and connectors, but can I accomplish the layout I want without the ugly white cord being in the way?

18AWG to 12AWG. The voltage and current is safe for the smaller wire but I just dont think I spliced it properly for soldering. How do you splice a smaller and larger wire?

Im trying to install a train horn and these are the parts I have and im having trouble wrapping my head around how everything gets wired now I know the fuse block should just go into the battery but im not sure how it goes from there i know the button panel has yellow as ground and I believe theres a red wire acting as power that comes from each button so does the red wire from the button just run to the red wire on the horn and then ground out the horn and if so where do they connect to the fuse block the only experience i have with this is underglow on a different car and that was a simple kit you just connect red and black to the battery but I wanna be nicer and safer about it because I also wanna add fog lights and a light bar later on

So do the grounds from button and horn run to the fuse box and then the reds to each other and it works? It makes sense in my head but I cant be certain

Ive never wired anything before and im clueless when it comes to electricity. How can I wire this thing up?
