I bought a used SL500 with 21,000 miles on it. The automobile appears to be in excellent shape other than an intermittent drip from the left top locking pin.

By chance, I went through every one of the fuses to check to see if there were any blown out fuses only to find that with a couple of the fuses, there were either a higher amp or a lower amp put in the slot. With so many fuses, I went back and double checked each one.

I cannot believe that this is a standard practice.

I am assuming that the correct size fuse should always be used in the proper slot. Am I correct or are there any hidden MB secrets that I am not aware of regarding putting a higher fuse in a certain slot.
