First gen blowing ignition fuses?

[68amc]

My 92 eddie blows main ignition fuses. I have no clue why or even where to look. Its blowing the 60amp in the power distribution box. About 2 months ago i was driving a hit a pothole and it just shut down, i popped the hood shook some wires, replaced the fuse and it was good. I drove it until yesterday with no problems. I put it in reverse and it just shut off again. This time no luck with anything. Can someone please point me in the right direction?? Thanks!

It sounds like you have a wire rubbing somewhere and it has finally worn through the insulation. When you hit that pothole it probably grounded the circuit out. The only way to find it is to trace out the circuit and find the spot where the wire is grounding out. I would start where you wiggled the wires and also where any wires in that circuit are close to the frame or body.
