Before trying to hook up your player, make sure it is plugged in and turns on when you press the “power” button. Usually a small light or welcome message appears when the DVD player is working correctly. There are at three common ways to connect a DVD player, and each needs a different cable to work. Your DVD player should come with all of the appropriate cords, but you need to check which connections your TV accepts as well. The three most common are. HDMI connections are the highest quality connections and you only need one cord for both the audio and video. There are three prongs at either end– red, yellow, and white — and they match up to corresponding colored inputs on both the TV and DVD player.


Trailer Lights Will Eventually Fail! Avoid legal and regulatory citations and fines. Save time and money by testing your trailer lights with Light Check.

So for about $40 you get the advantage of not having to cut any holes in your dry wall for the switch box, or to feed your fish tape up to the light box, along with not having to buy a switch box, switch, ROMEX, and wire nuts (~$8-$16 depending on the length of Romex).

Some people will tap off the middle post to get a 12V supply, though this is generally a bad idea – explained below: You can even tap off the “top” battery as well for another 12V circuit, but please note that the ground – for this circuit will not be the same as your bus ground: Because the grounds are different for this second circuit, this means that you can’t power anything with it that is grounded through it’s installation to your bus.

The 12V circuit that this creates will always be on, you can make it be switched such as by the ignition switch by simply wiring it through a 24V relay. This is generally a bad idea because it means your draw on your batteries is out of balance unless you match the two 12V circuits One battery will continuously lose more charge than the other and then be at a lower voltage. The charger on your bus does not charge the two batteries separately, it simply places 28V or so across the battery terminals.

This means that eventually one of your batteries will die, or the other will be overcharged or both. Owners of some 24V buses such as MCI may note that the manufacturer has a 12V tap coming off the center posts and assume that this is a safe place to get 12V.

My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”?

I had previously suspected that some tadpoles are late undergoing metamorphosis, but this one really missed the boat. Is this a recognised phenomenon, and what is the explanation? Is there an accepted ratio or does it vary, and if so by how much?

Connect the “source” wire to the bottom terminal of the switch and the other black wire to the top terminal. In this picture, you can see the strip gauge on the back of the switch. This gauge is when you want to use the “quick-connect” method when wiring a light switch.

Have you ever been stuck behind a car that has faulty brake lights? Your frustration level can hit the roof as you’re trying to predict when this driver is about to brake or turn since his lights aren’t working. Or perhaps, his brake lights stay on indefinitely and you must stay a few cars’ lengths behind since you have no idea what maneuver he’ll be performing next. Without functioning brake lights, the incidence of rear-end collisions would certainly be much higher.

If one of your brake lights goes out, hopefully your first clue isn’t a cop pulling you over to let you know. If one of them does go out, you can probably fix it yourself if you know a little something about brake light wiring. The brake light wiring system in most cars is not overly complex. At one end, you have the lights themselves: At the other end is the brake switch, where the pedal presses down and creates contact that completes the circuit.

The system draws power from the car’s battery. If you’re planning some brake work or brake repair, need to rewire brake lights or are already in the middle of fixing brakes, this article will tell you how brake light wiring works.


They control the primarily the lights, horn, and ignition since mopeds tend to not have other electrical subsystems. But it is because of the bare bones nature that they exhibit some of the illogical problems. Loss of spark due to a brake light failure and that sort of tom-foolery. The majority of mopeds fall into the category of fixed-magnet, ac generator with simple points and condenser ignition and a balanced load for lighting with a common ground through the frame.

Bikes with blinkers installed in the system have blinker relays and voltage regulators primarily and may or may not have voltage rectifiers installed and a battery lighting system.

Wiring a Light Switch – End of Circuit The easiest place to wire a light switch is at the end of a circuit. This does not mean that you should plan all your circuits so that your light switches are necessarily at the end. A light in the middle of a circuit really isn’t that much harder.

1. Install a single-pole light switch by connecting the black wire entering the box to the bottom, brass-colored screw and the black wire leaving the the box to the top, brass-colored screw.

Hook up wire aligator clips on both ends Electrical tape For the most part, you will probably be using your volt meter. If there’s more than that, see if you can tighten the belt. Do this by removing one or more shims that’s between the two pulley halves. If after removing all the shims and there’s still too much play in the belt, then the belt is stretched and needs to be replaced.

Wire harness and connectors. Depending on the year of your VW, the regulator can be found under the rear seat left side or be mounted right on top the generator. If you have an alternator, then regulators are usually built in to the alternator itself. Typically, on a 6V car and older it’s mounted on top the generator a silver box. On a 12V car and on it’s usually under the rear seat off to the left.

In Ghia’s, I think the regulator is in the engine compartment and I believe that’s the same with the Bus. Anyway, check and make sure that the wires are on good and tight and not burned or damaged. Disconnect the battery cables, negative cable first then the positive. Inspect the battery posts, for a few bucks, you can buy a battery post cleaner or use a wire brush and clean the posts and the battery clamps.

There’s also a gooey gell that you can put on the posts once the cables are re-attached to help them from corrison build up.

What we need is a way to allow for a level switch to turn on and off without cycling the pump motor at the same time. This circuit can be used to control a pump that fills a tank. The first switch L is set at the minimum liquid level desired in the tank.

M1 Garand-BAR situation best: The only malfunction, is that occasionally it will double, which I have not had happen to me, but others firing it had it double about 5 different times, while I was present. Many semi-auto rifles have what some call a “Sweet Spot”, where the trigger will function with only a slight movement of the trigger from the recoil , and this is the suspected gremlin that jumps up after the first round fires. There is a “Hard Corps” of people that have absolutely no use they hate it and really don’t know anything about it for the M Johnson, and will relate many kinds of horror stories about them.

Maybe more horror stories than there were M Rifles built. I have seen and fired as many as 75 Johnson M Rifles, and I have not seen more than just a few malfunctions maybe as many as 10, counting the 5 times my own Johnson M has doubled! There were only about 20, of them built maybe less, because the records are not too comprehensive at least vague , which were built under contract to the Dutch Government.

I want them to come on only when in reverse as I have a led bar on the back of my top for a work light. I got the 16mm bolt lights from oznium. I have the lights mounted and the wire ran up to the two back alarm wires in the factory harness. I tried wiring the lights up with a relay to the back up alarm wires as the drawing above shows, but nothing happens when I put the Ranger in reverse other than a loud clicking noise.

Most modern switches have screw terminals on each side and may also have holes in the back to accept the end of the wire. You can easily loosen the screws on the side of the device with a standard screwdriver turning counterclockwise , but you may find getting the wires out of the back of the device tricky. To remove these wires, insert the blade of a small screwdriver into the slot under the hole into which the wire is inserted and push in as you pull the wire loose.

Pushing the blade of the screwdriver into the slot releases the grip on the inserted wire. Here are descriptions of the wires and where they go: The white neutral wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black hot wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red.

The present circuit of an automatic night light can very effectively put an end to this problem. Read here how to build it. Today everybody along with the politicians and the official authorities are busy putting forth their own opinions regarding the issue.

Print —Check local regulations for restrictions and permit requirements before beginning electrical work— The user of this information is responsible for following all applicable regulations and best practices when performing electrical work. If the user is unable to perform electrical work themselves, a qualified electrician should be consulted. However, some older metal boxes and most plastic boxes don’t have a terminal like this. Conductors include wires, devices like switches and receptacles, and some other metal parts.

Check here to calculate the number of conductors allowed in a box before adding new wiring, etc. The white wire is usually the neutral which is always connected directly to the source neutral, either at the source or through a splice in the switch box. The white wire may also be used to carry current when necessary. In these cases, it should be wrapped with electrical tape to mark it as hot.

The ground should be spliced with a short piece of wire and connected to each device and outlet box that has a grounding terminal. In these drawing the brass colored terminal represent the hot side of the device and the silver colored terminal represent the neutral. Ground wires and terminals are in green.
