TROUBLESHOOTING
4-2.5 Damage Cause and Remedy of Brush Alternator
Table15
PHENOMENA
CAUSE
REMEDY
Cannot generate
1.Switch is on the position
of "OFF".
1.Turn the switch to the
position "ON".
2,Worse connection of the
plug or the control panel.
2. Adjust the contactor of the
plug or the wires inside the
control panel.
3.The connection of the
capacitance contact is bad
or capacitance burns.
3.Connect the contactor well
or change capacitance.
4.The carbon brush wears
out or its positive pole and
its negative poles are
connected crossly.
4.Change the carbon brush or
make the wrong connection
right.
5.The second reel of the
alternator has turnoff.
' 5 Check the reel by the
Multimeter. And change the
stator if it needs.
6,The rotor has turnoff.
6,Check the reel by the
Multimeter and change the
rotor if it needs.
Low Voltage
1 l o w engine speed
1.Increase the engine speed.
2.Short-circuit of the rotor
reels. Capacitance burns,
2.Change capacitance first. If
the voltage is not high
enough, change the rotor.
3.Short-circuit of stator.
. 3.Chang the stator.
4.Adjust the resistance of
Capacitance. If the voltage
remains, change the stator
of the alternator
4.The sample voltage has
short circuit.
Others
1. Capacitance burns after
load. The voltage decreases,
even disappear.
1
•
Change capacitance.
2.After loading, the PTO
shaft skids, the voltage
decreases, and the
alternator overheats.
2.Disassemble the engine.
Maintain the PTO shaft
and the inside pole of the
rotor until the conic degree
reaches to the reasonable
level. Then reassemble
the engine.
3.Short-circuit of the rotor or
the stator makes the
alternator overheat. The
voltage decreases.
3.Change the stator or the
rotor.
If you are still having trouble, please contact with your nearest dealer or with
our company directly if necessary.
