I need a fuse box diagram for 1983 Dodge Power Ram

When the fuse keeps blowing, there is only one reason why. That is because there is a short, not because other fuses are missing. For example if the fuse is rated at 10amps, and the wire after the fuse is drawing more than 10 amps it will blow. If for example you put a bulb in series with the wire than is only drawing 2amps the fuse will not blow that is because you have put a load that is less than what the fuse is rated for. One way to trace a short is to start where the fuse is at. Find which is the wire connected to that fuse. one side of the fuse is connected to the battery and the other side goes to whatever device it supply, and there maybe several of them. Note what else do not work beside the turn signal, Most short occur where there is an electronic device. Since your car is an older model, it is unlikely to an electronic device, but a wiring may have been worked on and somehow a hot wire is touching the body of the car. If the fuse blows only when the key is in the on position, then logically you would look at the back where the rear lighting may have been worked on, thats because turn signal are always off when the key is off. If it blows even when the key is off then you know there is something else beside the turn signal that the fuse is connected to that is on even when the key is off such as tail lights because you can turn on the tail light with the ignition off. You get what I mean?
