12. AVR ANALYSIS
The following paragraph provides a procedure for the identification of the AVR failure and the proper filling in
of the annexed report form ((APPENDIX)).
All the checks and measurements specified herein must ALWAYS be performed with the AVR
disconnected from the alternator.
This document allows to identify the failures occurring in the AVR envelope, in the main components
and/or in the AVR power supply circuit.
The accuracy and steadiness of the regulation can only be verified in the final application for which
the
alternator is used.
IMPORTANT: in case of malfunction or if any AVR failure is detected, for any AVR claim to be accepted the
user must have carried out the preliminary procedure described herein and filled in the report form in its
entirety.
In case you experience any of the difficulties listed in this chapter please follow the troubleshooting and
repair procedure described
The report form includes the following sections:
