When checking for shorts, I have taken a fuse and soldered the stripped ends of some wire on the ends and connect it to a 2 pole turn signal flasher unit. the flasher takes the electrical load and lets you unlpug stuff until it stops clicking, then you have found your culprit, without using up a bunch of fuses.

That brings me to my similar problem:
1993 190e 2.3, blowing fuse #1. I have mitchell-on-demand with its limited information, and have unplugged everything I can find that is related to that circuit.
Does anyone have experience removing the fuse box, I cant seem to find the forward bolt from the top side (I can see it from the bottom) I feel that my short is in the the box itself, and is this a common problem?

Thanks,
