If your home has copper water pipes, then run a wire to the closest pipe and clamp it right to it.

Looking for ground wire for Technics SL-B260U Turntable


There's nothing special about a ground wire! All you need is a piece of single standard wire that connects to an earth point on either the receiver - generally a screw terminal, or a earth point in your home. Say a metal pipe. Any electrical shop will have a strand of wire that will do the job.

Grounding issue


The preferred approach is to run a ground cable from the turntable to the ground post on the back of your preamp or receiver. This keeps buzz and hum out of the audio signal. If your receiver doesn't have a ground post, you'll have to connect the ground to one of the RCA signal jacks. In both cases the question is, when you have two grounds, which one to connect? You'll have to determine this by trial and error. My guess is you'll get the best results by connecting both, so start with this arrangement. Connect the turntable's audio cables from its RCA jacks to the receiver, select the phono input, and turn it on (with the volume turned down). Turn up the volume until you can hear hum or buzz. Then connect a piece of wire to the ground post on the turntable panel and touch the other end to the ground post on the receiver or to the RCA jack/plug's outer ring. If the hum/buzz goes away, you're good to go and can connect the wire permanently. If not, try the ground cables individually and use the connection that works best.

This is a grounding issue either between pieces of equipment or inside the receiver itself.
There are other possible causes, but this will almost always be a grounding issue.
I recommend unplugging everything and hooking it up piece by piece till the buzz return to isolate the issue.
IE - start with nothing but the receiver and speakers hooked up. Turn on the radio. If the speakers buzz, the receiver has an issue and needs to be repaired or replaced.

If there's no buzz, hook up the DVD player. If the buzz returns, there's some issue between the DVD and the receiver....
If the buzz hasn't returned, hook up the.....<insert name of next piece of equipment here>
you get the idea.

I'm trying to install a new panasonic car stereo into a 2005 dodge dakota and cannot get power to the radio to run. I have the recommended car harness and still can't get the thing to work. can you give...


take digital voltmeter and follow the harness colors to check for powers and grounds

red is ignition switched 12 volts only when car is running
yellow is constant power 12 volts on all the time from battery

black is ground this is the most important wire in the radio circuit if you dont have it grounded good you wont get a complete circuit .

to ground a radio either use the factory ground or find a piece of metal that is connected to the truck frame and scrape the area clean from paint or oils or grease and take a star washer and screw down the wire or bolt down the wire to get a good ground make all ground in one area so you dont get a ground loop .....

Tring to wire trailer prug. When I hook up signal light or any other lights all wires become live?


The piece that you may be missing is GROUND. You must have a wired ground. You cannot rely on the hitch to carry a circuit. Grounding though the frame deteriorates over time. Sometimes you have to run a ground wire to the tail lights.

I am trying to run speaker wires to receiver. wires from subwofer


hello their, running speaker wires that are a thicker gauge will allow you less distortion as well as more power. when the wires are extremely small, it;s like pushing air threw a very small tube, the larger the tube the less electrical resistance you will encore, their is also a tip their, if you have a 1,200 watt mono single channel amp running @ 1 hertz you would be better off running thick ground and power wires, threw a distribution block before the fuse to the battery, the fuse is actually necessary cause 75 amp's running direct threw a wire is dangerous if not properly fused. fires can start, as well as damage to any electronic equipment. please use proper fusing (example taking a wire and briefly touching ground to power will destroy and violently ark a wire apart.)

Electrical problem with the dash.


This wiring problem can be much more costly, and time consuming, than you want to take on.
Professional mechanics cringe, when a wiring problem of this magnitude comes their way!

It's probably a bad ground for the instrument cluster.
The instrument cluster housing is plastic. There is a flat, thin, 2 to 3 inch wide, piece of plastic that is the wiring harness for this instrument cluster.
In this flat piece of plastic, are thin flat copper strips. These are like wires, to conduct the electricity to the gauges, lights, and the rest of the instrumentation.

Since the plastic instrument cluster is not metal, and therefore it can't be used as a Ground source, the flat piece of plastic I mentioned above, has a Ground wire to it. May be more than one.

This ground wire/s could have corrosion on the terminal end, where it attaches to the truck body.
Bad ground, everything goes haywire. The ground wires, might loose on the terminals used for the flat piece of plastic.

Another source of a bad ground problem overlooked, is that the cab of a truck receives it's,
Main ground from the engine.

There should be Two ground straps, coming from the firewall over to the engine. Sometimes, when the upper part of an engine, or the engine is replaced, the mechanic neglects to reinstall these ground straps.

Sometimes just one ground strap is reinstalled, and this is No good!
Also both terminal ends of these ground straps are a good source for corrosion to develop.
Corrosion makes a bad contact.

I myself would take the truck back.

How do I ground my receiver?


Use the black wire in the wiring harness, and connect it to the black wire in the car's harness. This grounds the receiver. If you have a chassis ground (a braided cable) for the receiver, ground it to any metal screw in a metal frame piece under the dash.
