Part 6 Service Diagnosis
RXYMQ4-6AYFK
Perform the following procedures prior to check.
(1) Power OFF.
(2) Remove all the wiring connected to the PCB where power transistors are mounted on.
Point of Measurement and Judgment Criteria
Turn OFF the power supply. Then, after a lapse of 10 minutes or more, make measurement of
resistance.
When using the analog type of multimeter,
make measurement in resistance measurement mode in the x1 k
range.
When using the digital type of multimeter, make measurement in diode check mode.
Preparation
Multimeter
Prepare the analog type of multimeter.
For the digital type of multimeter, those with
diode check function are available for the
checking.
