4 Load, no voltage
Possible Cause
• Short-circuit in on-board cir-
cuit.
• faulty rectifier.
• Voltage Regulator (AVR)
faulty.
7
5 Load, voltage too high or low
Possible Cause
• Incorrect engine speed.
• Incorrect voltage setting on
voltage regulator.
56
Solution
• Trace the short-circuit and
repair.
• Replace rectifier.
• Replace Voltage regulator
(AVR).
Solution
• Check engine speed and re-
adjust as required.
• Adjust to the correct volt-
age.
GHS6.5, GHS8, GHS14, GHS24, GLS6.5, GLS14 and GLS25
6 Load, voltage oscillates
Possible Cause
• Engine runs irregularly due to
lack of fuel, faulty or wrongly
set fuel pump.
• Poor electrical connections.
• Incorrect Voltage Regulator
(AVR) stability setting.
• Voltage Regulator (AVR)
faulty.

Solution
• Ensure the supply of enough
clean water-free fuel.
Have the fuel pump checked
by a specialist and repair or
re-adjust as required.
• Repair the connections.
• Readjust the stability.
• Replace Voltage regulator
(AVR).
