Not if you're using a typical modern multimeter (e.g. the cheapo kind
from Radio Shack) that is powered by one or two 1.5v batteries. The
water will conduct some electricity but not enough to confuse your
results since you're just testing for when an open circuit closes.
The real danger is when the lady of the house discovers you're using her
stove and candy thermometer to test auto parts.
