My '81 Accord 5 speed keeps blowing #6 fuse (10 amp), marked "Turn signal lights, back up lights and fuel gauge". When the fuse blows, it also knocks out my tachometer, temperature gauge and the battery light comes on. I recently had a tune up done and I'm wondering if a wire to the tach could be shorting out somewhere. I'm having trouble locating the problem. Any ideas? Thanks in advance!

 

The tach should get it's signal from a blue wire at the distributor. You could follow it from there, but I really have no idea since it's so old.
