engine fuses blowing

twice now the ten and 20 amp engine fuses have blown. i noticed that when this happened the odometer indicator flashed on then off. i do have the 3 resister problem and have been putting off fixing the problem..could this cause the fuse blowing?. well, i am going to attemped the odometer fix to see. i will let all know.

mine was blowing the # 8 fuse in the engine compartment. It turned out to be the starter silioid I pulled the starter found a bur inside the silioid sanded it oiled it up no problems since
