Hi, my old faithful fluke 77 multimeter has stopped reading DC and AC current. It still reads Ohms, Volts and continuity, just not current. I found this guide here... http://assets.fluke.com/manuals/75_77___omeng0900.pdf although it doesn't help that the 77 pcb is slightly different to the diagram shown. i.e. I don't have a couple of the components or two fuse holders in mine. With components being tested with another multimeter still on the fluke 77 pcb, nothing seems to be faulty. I checked the fuseable resistors and i can't seem to find anything faulty. Has anybody else had this problem or know what component could be at fault? Thanks.
