I have an 83 4wd wagon that has now blown the fuse for the coil three times. Each time seems unrelated to the others i cant seem to find pattern. I been looking for a short that would lead to this but the wires all run through the loom and i cant follow them.

The coil has three wires on the positive and two on the negitive, On the positive side one is power one is for the tack, and on the negitive one is the ground i dont know what the other two wires do( one positive and one negitive)

Thanks

David

Is the fuse blowing out immediately when it is put in?

 

One thing you can do to help find the problem is replace the fuse with some jumper wires tied to good load, like a headlight, and start disconnecting suspected wires tied to the problem area. When you disconnect the wire leading to the short the light will go dimmer or turn off, depending if there are other devices drawing current. If nothing else is drawing current then the light will go out.

Hey David This is Jerry,you have 3 wires the yellow wires go to the ground side of the coil and the red boot covered black with white stripe wire gose to the hot side of the coil. Hopes this helps you Thanks Jerry

The fuse dont blow right away after the first one blew i drove for a couple days and before it blew, the next one was after a hour or so. I dont want to drive the car knowing at any minute the car could just stop running. In my mind the draw the draw on circuit should be constant, because the only thing on that circuit is the coil. If some one has a wiring diagram of that circuit that they could scan it would help a lot.

 

Now that i think of it the battery gadge on the dash goes out too.

Im still trying to identify the five wires coming off the coil.

You are correct that current should be fairly constant, depending what is in the circuit. There is most likely a current surge caused be an intermittant failure to ground somewhere. It could be the coil doing this or something else.
