I don't think what you have going on is a short if so it would blow a fuse. I think it is a ground problem. I would check all grounds from the battery to the engine, engine to fire wall and battery to frame. Remove and clean as often there is a disimiliar metal problem that causes corroision.
For many years Japanese vehicles have had a system where a fuse opens or there is a loss of a light or voltage and odd light will light on the dash. I have seen this the early 70's. Good luck
