If a powerful audio system is installed in the car, a sound distortion is mighting, flashing headlights. To fragilely enjoying loud music in the car, parallel to the automagneto capacitor fell. Before connecting, the device's serviceability is checked.
1
Condensate inspection. When leakage, overheating occurs and the case swollen, stains appear.
2
To the device, observing the polarity, the apparatus of an ohmeter is connected, the charging process begins. And as a result, the rapid increase in resistance from 0 to infinity. If the resistance remains zero, there was a breakdown. The multimeter when the cliff will show on the dial unit, the beep sounds.
3
To a non-polar condenser, connect a multimeter with a mega measurement limit. The working capacitors will indicate 2 or more mega.
4
To detect the leakage of the capacitor several times (with an interval 2-3 s) connects to the Ommeter. If the arrow moves to zero and back, the condenser is faulty.
5
Fully charged condenser Disconnect from the power supply. After a voltmeter time, check the voltage. The electrolytic capacitor retains a charge of up to 30 minutes. Other types - more than 2 hours.
6
Definition of rupture. A chain is built with a sequentially connected resistor, an AC ammeter and a condenser. The diagram closes on the source of the AC. Its voltage is 20% and less from the rated voltage of the condenser. If there is no current in the chain, the condenser is faulty.
7
Most often, the decrease in capacity is in electrolytic capacitors. The container is measured by the LC meter or otherwise elkemetrom. Connect it and compare measurements with marking on condensate.
Before checking the condenser, it needs to be disconnected from the chains and discharge. Otherwise, you can get injured or damage the equipment.
