AC ** LEAKAGE** or AC **RIPPLE** ? Leakage is current leaking across
from the power
lines, and is a safety problem. Ripple is a variation in the DC
voltage, generally at twice the
power line frequency. Leakage would be measured from the output
terminals to the safety
ground prong at the power outlet. Ripple would be measured between the
+ and - terminal.

More caps would smooth the ripple, but would not affect the leakage problem.

Most voltmeters will read the ripple correctly in the AC position.
