These are ground wires and can be attached to the chassis anywhere where they will fit.

How do I fix my 8 track player?

These are operate by a solenoid and a ratchet that moves the head up and down. Pressing the channel changing button activates the solenoid. A metal strip on the tape also activates the solenoid. In this case either the solenoid has stopped working, it might be stuck! Or the ratchet is damaged. Most of the time it sticks on channel 4 with this fault, though it can stick on others.

2005 Trailblazer, squeaking noise in the right and left rear after vehicle warms up after driving several miles and begins squeaking when hitting minor bumps in the road..

If it has a multi-link rear suspension that is fitted with rose joints it could be one or more of those.

Mostly in the case of vehicle noise assistants are needed to bounce the car to duplicate the noise while someone is underneath with a stethoscope listening.

Careful inspection with a good light can sometimes show something that has been moving that shouldn't be moving. Such things are often able to be seen by a different coloured line around the object or some rusty-coloured powder.

A vehicle mechanic would hope for a more comprehensive description than "squeak" as an aid to recognising it and locating it. Is it for instance, a rubber, plastic or metal type noise? Is it a noise that is heard only when large bumps are driven over or is it a more rapid jiggly sort of noise?
Accurately describing symptoms by painting a sound picture with words is of invaluable help...

My sony mds-303 is ejecting new disc and saying disc error

I had the same problem. Take the top off and wind the loading wheel until the mechanism engages and loads - but with no disc in place. Then unplug the power and look through the top. You will see the lens. Clean with rubbing alcohol and a q tipi and dry with a clean q tip. Try playing a disc

No output to rear jacks

It's hard to do this long distance, but I have a feeling the problem is with your disc or your laser, not your connections. A distant third possibility is the deck's transport.

First, plug the deck into an amp, and make sure you have connected it to the right place. (It is very easy to get tripped up by tape inputs and tape monitors.)

I suspect that you accidentally erased the disc. So let's check. Play an MD that you are SURE has something on it and see if anything at all is coming through the amp and speakers. Be sure to look at the display to see if the disc is actually playing a track.

Then try recording something on the disc you have. Be sure to enable the disc to record. The little white tab on the bottom left has to be closed. If it is open the disc will not record. Make sure it is all the way closed, too. Do this by opening it and then closing it with a thumbnail or small screwdriver.

When you record, see if the record meter shows that something is actually going into your deck.

You should also see if the metal protective tab is still there (front right center), and try to jiggle it to see that it is not stuck. Don't force it - just jiggle it. Memorex discs are famous for having that part fail. That part has to slide down for your disc to play or record. This will make a lot more sense if you take the lid off your deck and watch the mechanism work.

1) Be sure there is something on your disc.
2) With the lid off see if the disc is actually turning.
3) Look at the display to see if it tells you that the disc is playing.
4) In case you erased your disc, try recording something on it or on a different disc). Check the display as it does so, and look at the transport to see if anything is turning.

If nothing is turning or moving, it MAY be dirt or it may be grease where grease shouldn't be or no grease where grease should be. That is unlikely, but check it out. What do you have to lose?

If everything is moving but nothing records and nothing plays back, your laser is dead. And they are not cheap. Fortunately, there are a gazillion MD decks on eBay.

When all else fails, read the operating instructions -

My JVC CA-hvd7 is showing 'protect' and I can't

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

MD player windows keep saying "no disc" when a disc is inserted. This started after the door starting getting sticky opening and closing. Any help would be great. Thanks

The little switch that detects the disc is inserted goes bad quite often on all of these sony home MD recorders. Do an online search as I have seen a step by step approach on it's repair. Make sure to UNPLUG the unit before removing any covers and poking-around inside. Good luck,

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.
