Everything is not long-term, in daily use there will inevitably be a variety of problems, marine electrical opportunities what failures, in order to better understand, today to give you a detailed description of the marine motor does not generate electricity or voltage abnormal reasons and measures taken.

　　Cause analysis of non-power generation or abnormal voltage

　　(1) Fuse break

　　(2) Voltmeter damage

　　(3) Voltmeter inaccuracy

　　(4) Poor contact of voltage regulator pins

　　(5) Rotary Rectifier Module Damage

　　(6) Loss of remanence

　　(7) Wiring error

　　(8) Exciter magnetic field coil breaking

　　(9) Joint loosening or poor contact

　　(10) Breaking of armature coil of generator

　　(11) Short Circuit of Armature Coil of Generator

　　(12) Breaking or Short Circuit of Armature Coil of Exciter

　　(13) Abnormal speed

　　(14) Switch-off circuit action with regulator protection

　　(15) Regulator damage

　　Disposal methods for non-power generation or abnormal voltage of marine motors

　　(1) After confirming that the line is normal, replace the fuse and reclose.

　　(2) Measure the generator terminal voltage directly with the multimeter voltage bar.

　　(3) Timely calibration of the meter shall be replaced if it is not permitted.

　　(4) Check whether the voltage regulator pins of 50Hz, 60Hz and 6, 7 are loosened or not.

　　(5) Rotating rectifier module to main rotor

　　Remove the door multimeter or light bulb from the magnetic field connection to measure the rotating rectifier module. If damaged, it needs to be replaced.

　　(6) The battery 12V is connected to the stator coil of the AC exciter through a diode, and the positive pole is connected to X, and the negative pole touches XX (about 2 seconds).

　　(7) Detailed inspection and connection according to wiring diagram

　　(8) Wrap the broken wires, solder them firmly with tin solder and wrap them with external insulating materials.

　　(9) After wiping the joint clean, reconnect it

　　(10) Find out the break and re-weld the bandage

　　(11) Short circuit may cause serious fever, so the coil should be removed.

　　(12) Find out the fault point and replace the coil

　　(13) Check the speed of generator with speed or frequency meter

　　(14) Adjust the regulator after correction according to the regulator instructions

　　(15) Replacement of regulators
