Voltage is pressure, amp is flow.

Think of an air tank, just because it's at 100psi doesn't necessarily mean there is air flowing out. It could be sealed up tight, and it will stay 100psi forever. Crack open a bleeder valve, and now you have flow, and now that air pressure will drop.

Measuring voltage won't tell you the drain. You need a multimeter that will measure current draw. Repeat your same test, same configuration, with a meter on an amp setting, and start pulling your fuses. The one that causes the meter to drop the most is your culprit.
