98 SL2 clicking noise in rear passenger wheel well
 

not sure whats making the noise i havent taken apart yet. charged the battery. and without starting it. i opened the door and i heard a really faint clicking kind of like a relay but in a very odd pattern. AND a pretty long time. (till it drained battery) tracked it to rear passenger side wheel well near the strut. only thing i can think thats electrical thats near that area is the fuel pump. if ANYONE can help id greatly appreciate it. i am pretty mechanically inclined. so i am going to pull apart tonight. and if i figure out the problem i will update post with solution. but any info till then would be helpful and appreciated

Need to fill in some missing info. Parasitic draw? How long to drain?
I await your findings.
