I'm renewing all of the fuses in our '76 240D. The main fuse box was easy; I followed the printed diagram inside the cover and replaced everything with correct fuses. The smaller fuse boxes sprinkled around the engine, however, have kept me guessing.
I do not know what the different fuses do and I do not know what amp rating is appropriate.
Due to the fact that some of the fuses in the main box were of the wrong value I suspect that these fuses could be wrong too.
Also, which of these fuse boxes is linked to the glow plug relay? I recently replaced our plugs and the indicator light is no longer working.
Thanks, theob
