Tests for tachometer and sender unit

Fuse 13 keeps blowing. I have traced the problem to the circuit that powers the instrument panel; wire 182 has only 6 ohms to ground with the air mass and ECU unplugged. When I checked the power leads from fuse 13, I found that removal of lead 182 increased the resistance to ground to values that would not blow the fuse. Now I am not sure how the check the tachometer without trying a new one. Any ideas to a rather complex problem would be appreciated.
