However, this emitted noise may have similarities to that of a belt, so a high hiss. The concern can arise from a electrical failure, this remains rather ordinary. If it happens that the voltage useful for the good activity of this volvo 940 remains deficient, it can usually be seen in the lack of power of the lights or lights in the car. If ever the lack of power is excessive, it happens that the battery indicator can be in operation. So as to proceed with a good diagnostic of this concern, it remains possible to use a voltmeter and to probe the tension on the + and - of its battery, the engine obviously runs. Assuming that the voltage turns out to be lower than that recommended on the battery, the problem can therefore come from the alternator. In this case, it will generally have to be changed.
