S127 Mechanical noise in the amplifier area

			Test results
1	COMPONENT CONCERNED	AMPLIFIER FASTENER CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Amplifier fasteners	Check that the fixing points for the amplifier have been properly tightened: screws, bands, ties, etc...	Go to Step 2	Incorrect fastening of the amplifier	Restore the correct fastening of the amplifier
2	COMPONENT CONCERNED	AMPLIFIER FASTENER CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Amplifier fasteners	Check that there are no cracks or slots between the brackets/mounts touching the surfaces of the amplifier or of the bodywork	Go to Step 3	Cracks or slots between the brackets/mounts touching the surfaces of the amplifier or of the bodywork	Restore the correct fastening of the amplifier by fitting some soft stuffing (foam, rubber, paper) in the relevant areas
3	COMPONENT CONCERNED	CHECK AMPLIFIER OPERATION	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Amplifier	Check that operation of the amplifier is correct shaking it to find out possible loose objects inside	Go to Step 4	The amplifier is damaged	Replace the amplifier Op. 5580T42 BOSE SOUND SYSTEM AMPLIFIER - R.R.
4	COMPONENT CONCERNED	CHECK AMPLIFIER OPERATION	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Amplifier	Check that operation of the amplifier is correct identifying contact points or gaps among the different components of the amplifier (holding the amplifier and beating it more times on different points on each side; the response to this movement must be a dull sound, without any vibration).	End of diagnosis	The amplifier is damaged	Replace the amplifier Op. 5580T42
