Fault finding
Verify the two CH1 F1001 and F1002 fuses and the
two CH2 F2001 and F2002 fuses by means of a digital
multimeter set to Ohm.
In case of fault in one of the fuses we recommend to
check the condition of the Mosfets of every channel.
The test can be done by measuring the resistance value
between the pins of the output mosfets assembled on
the output stage board.
Here below the mosfets related to each channel:
Q1001, Q1002, Q1003, Q1004 channel 1
Q2001, Q2002, Q2003, Q2004 channel 2
Portrayed in (Fig. 48) is the location of the Mosfets.
In case of faulty Fuses and/or faulty Mosfets ask for the
KT000805.R K LGT AMP 1CH KIT
(Fig. 48)
