: Blown gauge fuse

Hi everyone.
Its been a long while since I posted, but I need some help. My recently purchased '73 coupe deVille has been running well, however now seems to blow the 10 amp gauge fuse. I noticed this when I went to start her, and saw the "trunk" light on. This stayed on, and the gen light came on. No other idiot lights (except eng. temp) work. After chasing things down, I found the blown fuse. A newly installed fuse blew immediately. Interesting, a volt check of the alternator shows it putting out only about 12 volts. Anyone have any thoughts???

A blown fuse means a 12 volt wire is grounded against metal somewhere. Try leaving the trunk open when replacing the fuse. Then start it and post back. Without a wiring schematic to know what wires are involved with that fused circuit, its a guess on anybodys answer. A gauge fuse usually controls dash illumination and taillights in that circuit.
