Fault Finding Table
GHS4
Fault Finding, generator
Possible Cause
• Loss of residual magnetism.
• Stator windings short-circuit
or poor connections.
• faulty capacitor.
• Rotor windings short-circuit
or poor connections.
• Interrupted or short-circuit in
diode.
Solution
• Connect a 2 Volt battery for
a short period to the capaci-
tor clamps to regenerate the
field.
• Check the winding resist-
ance. See ‘Technical Data’
for resistance values.
• Replace capacitor.
• Check the winding resist-
ance. See ‘Technical Data’
for resistance values.
• Replace the diode on the
rotor.
2 No load, Voltage too high or too low
Possible Cause
• Incorrect engine speed.
Solution
• Check engine speed and re-
set if necessary.
3 No load, Voltage oscillates
Possible Cause
• Engine runs irregularly
due to lack
of fuel, faulty
or wrongly set fuel pump.
Solution
• Ensure the supply of enough
clean water-free fuel,
or:
Have the fuel pump checked
by a specialist and repair or
re-adjust as required.
