Anything is not for a long time, in the daily use will inevitably appear a variety of problems, the ship electricity opportunity what fault, in order to better understand, today to give you a detailed introduction of the Marine motor does not generate electricity or abnormal voltage reasons and measures taken.

　　Analysis of reasons for non-generating or abnormal voltage

　　(1) the fuse is broken

　　(2) voltmeter damage

　　(3) voltmeter is not allowed

　　(4) poor contact of voltage regulator pins

　　(5) the rotating rectifier module is damaged

　　(6) loss of remanence

　　(7) wrong wiring

　　(8) the magnetic field coil of the exciter is broken

　　(9) loose joint or poor contact

　　(10) the armature coil of the generator is broken

　　(11) generator armature coil short circuit

　　(12) excitation armature coil break or short circuit

　　(13) abnormal speed

　　(14) switch off circuit action of regulator protection

　　(15) the regulator is damaged

　　Marine motor does not generate electricity or abnormal voltage treatment

　　(1) after confirming that the circuit is normal, replace the fuse and then close the switch.

　　(2) directly measure the generator terminal voltage with the multimeter voltage range.

　　(3) the electricity meter shall be regularly calibrated. If it is not allowed, it shall be replaced

　　(4) check whether the voltage regulator 50Hz, 60Hz and 6 and 7 pins are loose

　　(5) lead the rotating rectifier module to the host rotor

　　The magnetic field connection wire is removed and the rotating rectification module can be measured with a multimeter or a light bulb. If damaged, it needs to be replaced.

　　(6) the 12V battery is connected to the stator coil of the ac exciter through a diode for magnetization -- once, the positive pole is connected to X, and the negative pole is connected to XX(about 2 seconds).

　　(7) check it in detail and connect it with the wiring diagram

　　(8) twist the broken wire, weld it firmly with tin and wrap it with insulation material externally.

　　(9) clean the joint and reconnect it

　　(10) find the break point and re-weld and wrap it

　　(11) short circuit can cause serious heating phenomenon, should be removed and replaced coil

　　(12) find the fault point and replace the coil

　　(13) check the generator speed with the speed or frequency meter

　　(14) adjust the regulator after correction according to the regulator manual

　　(15) change the regulator
