An year ago, I extended the branch circuit from an outlet in my garage
to outside the garage (into the open yard) to provide a couple of
outlets to be able to use electrical power tools in the yard. I used
outdoor type sealed boxes for the outlets, however I did not change
the circuit breaker at the main panel to GFI type. I have regular
breakers on ALL the branches in my house. Everything worked fine till
the last week.

There was heavy rain last week and the outlet box in the yard got
water into it. As a result (I think) the outlets in the yard and
garage are not working (no juice). Curiously, the 2 outlets in the 2
bathrooms on the second floor are also not working. I don't know if
this is just a coincidence and if the bathroom outlets are on the same
branch as the garage/yeard outlets. Everything else in the house is
working fine.

I opened the outlets and checked the wires for connections (they are
OK) and any burnout (none) and checked for juice with electrical
tester and found no juice. Then I checked the cable visually to see if
any part of it has burned and it looks OK. I could not check the cable
that is inside the walls. Then I tested all the breakers and they all
are getting the juice (don't know if they are putting out the
juice....how to I check that?).

Well...this is where I am stuck. I don't know which breaker is for the
branch circuit for the garage and bathrooms and I don't know how to
check for a defective breaker. No breaker was tripped off and they all
seem to be mechanically working.

Can someone provide tips to me as to how I should go about diagnosing
and repairing this problem short of getting an electrician? Thanks in
advance.
