4.4 (*) Measuring the alternator insulation
resistance
A 500 V megger is required to measure the alternator insulation
resistance.
If the N-terminal is connected to the earthing system, it must be
disconnected from the earth terminal. Disconnect the AVR.
Connect the megger between the earth terminal and terminal L1
and generate a voltage of 500 V. The scale must indicate a
resistance of at least 5 MΩ.
Refer to the alternator operating and maintenance instructions for
more details.
Before carrying out any maintenance activity, check that the starter switch is in position O and that no electrical power is
present on the terminals.
