7.3 Alternator trouble

Trouble Cause
No voltage or voltage is 1.Winding is cut
insufficient while
generator set
2.Wiring terminal is loose
running
3.Wiring terminal is defective
4.Speed is too low
Voltage is unstable 1.Speed is unstable
2.AVR is defective
Alternator overheats 1.Overload running
2.Vent-pipe inside the alternator is
clogged
Voltage is too high 1.Speed is too high
2.AVR is defective
Voltage is too low while 1.Speed is too low
running without load
2.AVR is defective
Voltage is correct without 1.Speed setting is incorrect
load, but too low under
2.Short circuit on the rotor
load
3.Armature
defective
Voltage disappears while 1.Winding of magnetic field is cut
running
2.Rotor of excitation is defective
3.AVR is defective
Solution

necessary
2.Check to see if lubricating oil filter is
working properly
3.Clean or change air filter element
4.Check the fuel injection pump element
and delivery valve assembly, replace if
necessary
1.Select good quality fuel
2.Clean or change air filter element
3.Adjust the loads to meet the rated output
