If you suspect the Front Board to be faulted we recommend as a quickest way to find if the
Front Board is faulty, Doing by elimination – Just replace temporarily the Front Board with
another working one and thus make sure if the problem is within the Front Board or
somewhere else.
Check all connection of the Front Board, following the wiring diagram that can be found within
this maintenance manual.
Check main and Charging fuses, located near the rear wheels.
Also always check related function switch , as example Light does not work , first check the
light switch for continuity ,when is in ON position. Use the wiring diagram to figure the proper
terminals to check each function switch terminals.
