Service Diagnosis
Multimeter
(DC. voltage range)
To prevent an electrical shock, use a multimeter to check that the voltage between FU2 and
DC– is 50 V or less.
The surface of the test points (DC–) may be covered with the coating. Be sure to make firm
contact between the multimeter probes and the test points.
