10.TROUBLE SHOOTING FOR E1X KE SERIES
FAULT
Alternator does not excite
Low no-load voltage
Correct no-load voltage but too low with load
Correct no-load voltage but too high with load
Unstable voltage
Noisy Functioning
CAUSES
1) Insufficient residual voltage
2) Connection break
3) Broken fixed diode bridge
4) Broken rotating diode bridge
5) Insufficient speed
6) Windings breakdown
7) Broken compound
8) Broken voltage regulator
1) Low speed
2) Winding failure
3) Broken fixed diode bridge
4) Broken rotating diode bridge
5) Broken compoundr
6) Broken voltage regulator
7) Wrong setting of voltage regulator
1) Low speed with load
2) Compound is broken
3) Broken voltage regulator
4) Defective winding rotor
5) Load is too high
1) Appliances with capacitors on the load
2) Compound is broken
3) Voltage regulator is broken
4) Wrong connection of the phases
1) Rotating mass is too small
2) Uneven speed
1) Wrong coupling
2) Short circuit in windings or on load

6) Check winding resistance and replace damaged parts
7) Replace compound
8) Replace voltage regulator
1) Adjust rotating speed of the engine
2) Check resistances and replace damaged parts
3) Replace fixed diode bridge
4) Replace rotating diode bridge
5) Replace compound
6) Replace voltage regulator
7) Adjust voltage regulator potentiometer
1) Adjust rotating speed of the engine
2) Replace compound
3) Replace voltage regulator
4) Check rotor winding resistance and replace the rotor if broken
5) Reduce the load
