7.3. HOW TO DISCHARGE THE CAPACITOR ON REGULATOR C.B.A.
CAUTION:
1. Be sure to discharge the capacitor on RAGULATOR C.B.A. before disassembling the Regulator C.B.A.
2. Be careful of the high voltage circuit on Regulator C.B.A. when servicing.
[Discharging Procedure]
1. Remove the Rear case.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k
Ω
/5W).
(an equivalent type of resistor may be used.)
3. Put the resistor between both terminals of capacitor on Regulator C.B.A. for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is sufficiently lowered using a voltmeter.
