E21 fuse keeps blowing

Hi all,

The fuse that the gas gauge, coolant gauge and back-up lights on my
1981 320is keeps blowing for some reason. It's either fuse #8 or #10,
I can't remember. I can't figure out why the fuse keeps blowing. I
can put one in and know how much gas I have and the engine temperature,
and then the fuse blows within minutes. Could a bad coolant
temperature sender be causing the fuse to blow? Thanks.

Sure does sound like a short. These can be very difficult to debug. A bad
sensor of any kind might cause the problem. But, I would not replace any
sensor without knowing that it was bad. The short could also be the caused
by a problem with the cable somewhere.
However, it is most unlikely that a fuse blows for no reason.
