1. Turn OFF the power supply breaker.
2. Discharge all three capacitors completely.
3. Check that safety valve at the bottom of capacitor is not broken.
4. Check that vessel is not swollen or exploded.
5. Check that electrolytic liquid does not blow off.
6. Check that the normal charging characteristics are show in
continuity test by the tester.
C07, C08, C09 → 500µF/400V or 760µF/400V
1. Turn OFF the power supply breaker.
2. Discharge all three capacitors completely.
3 Check that the normal rectification characteristics are shown in continuity
test by the tester.
