Dangerous Symptom: Why You Can’t Ignore the Car Radio’s Whistle
Whistling in the speakers, which is a regular occurrence in used cars, indicates a fault in the wiring and the need to contact an intelligent electrician. However, many drivers believe that there is nothing wrong with such a “musical” problem and you can safely continue driving, although this is fundamentally wrong. And why, explains the portal “AvtoVzglyad”.

The music and commercials died down a bit, the air “cooled” for a fraction of a second, while the air was “filled” with a vicious whistle, depending directly on the actuation of the accelerator pedal. Yes, “melody” and “decibel” are somehow related to the rpm on the tachometer, which causes even more irritation. Probably the threads have soured or something has fallen into the block from the eternal shaking along our long-suffering ways. So it is located correctly. The point is small – to find a damaged thread.

About half of car owners give up and experience inconvenience right up to the next MOT: music does not directly affect speed, there is no time and extra money, so let yourself “foniten”. The other half decides to find out anyway and will be unpleasantly surprised: a nasty whistle is just a symptom, and the “extra note” still affects the operation of the internal combustion engine. And how!

Of course, the first things climb into the “music”. Because the “phonites” column means that the malfunction is hidden precisely in the contacts. However, the “block” for connecting the radio is intact and the wires look great, ringing confidently and causing no doubts. Having dismantled half the cabin and not finding circumstantial evidence of our argument, we return to the original one. The whistling of the speakers suggests that the “malfunction” should be looked for in a completely different place – under the hood.

Strangely enough, although car acoustics are sensitive to disturbances of the entire electrical wiring of the car, it reacts particularly reverently to the behavior of highly loaded contact groups. For example, a ground cable and a “plus”, as well as an armored wire. It is there, between the candles and the coils, that a break can occur, which will give a tip. How to search? Yes, it’s very simple: at night, which now begins at six in the evening, it is enough to open the hood and ask a neighbor to start the car.

Sparks matching New Year’s fireworks will tell you that high voltage wires need to be replaced. Immediately, strange starts of the engine will be remembered, and trimming the engine to a warm engine, and much more, which, like the column, indirectly suggested the need for maintenance. After checking and cleaning the “mass”, machining and tightening the clamps and replacing the armored wires, the problem will be solved in three cases out of four.

Of course, the master will find the malfunction faster, deftly handling the whistle “by experience”. It is he, the son of difficult mistakes, who is the most valuable difference between a car mechanic and a simple driver: he allows not only to fix breakdowns, but also not to be afraid to open the hood and find problems .

It seems that the time has come when all car owners are slowly beginning to acquire it – that is, experience. But how else, if the maintenance of a car at a gas station becomes prohibitively expensive…
