1. Measure the two ends of the battery with the DC voltage of the multimeter. The normal value should be about 3 volts. If the value is lower than the normal value, the battery should be replaced. Check whether the battery clamp is rusty again. If there is rust stain, clean it with sand cloth.
2. Check whether the fretting switch is in good contact with each other. If the switch is on or off by measuring the resistance of the multimeter, it can be judged whether the fretting switch is in good contact with each other. If the contact is good, the light emitting diode will be lit up. Otherwise, check the light-emitting diodes.
3. Check DC resistance of step-up transformer, two groups are 0 Euros, one group is about 150 Euros, this group is measured in the case of electrification, AC voltage is about 350 volts.
4. Check the oscillator. The tube has two models: S8050 and 5609. Note that the pin distribution is different. The collector (C) is 0 volts, the base (B) is 3.4 volts, the emitter (E) is 2.8 volts, and the difference between B and E is 0.6 - 0.8 volts.
5. Check the voltage doubling capacitance. It's good to measure capacitance on both ends of the road with a multimeter-TImes; the pointer does not deviate to zero. If it breaks down, the pointer will go to zero. When the capacitance is broken down, the electric mosquito pat will make a squeak when the electricity is turned on.
