I have a '87 CRX and the turn signals fuser, which aslo holds the clock, and the engine temerature, and fuel level, keeps burning no matter how large the fuser is, i aslo tried putting a nail to make it work but it gets hot and sparks comes out. I checked all the bulbs at the cabeling looks ok, what should i do next?

 

putting larger fuse in wont help ****..Just wastes more money..
You have a short in your system some where..Follow the wiring to see if there are any cuts/nicks in it..Because if the wiring has cuts in it and rubs against metal or gets wet it will blow a fuse..
