83 240d. having to replace the #8, i believe, fuse - the one that has the circuit that protects fuel and temperature guages, turnsignals, etc - on a regular basis. the question: how do i proceed, hopefully in some logical fashion, to find the short. sometimes i can drive all day and no problem. sometimes the fuse will blow after a few minutes. i have not been able to discern any correlation to what is happening in the car with the fuse's blowing. thank you.
