How can I trouble shoot a fuse that has a dead short in the circuit? It is # 19 on the fuse chart on page 6-6 of the owners manual for my 87 GN. It used to only blow at the track. I would put a new fuse in it and it was fine for a while. Now it blows immediately. The things on the circuit per the owner's manual are: clock, lighter (lighter works fine, must be on another circuit), glove box lamp, antenna (not hooked up-maybe the wire is dangling behind the radio), radio capacitor (what's that?) dome light (metal tabs are rusty), trunk and reading lights, door locks (they work with the alarm when i press the key fob- alarm is new and this was happening with old alarm too), under hood light, lights at floor board. I also have VDO gauges -clock and transmission temp-that were installed by prior owner. These don't work either. I tried disconnecting them at the guages and put in a new fuse which still blew immediately. Thanks.
