We just had a round of buses that Rat got in the side panel cut the starter interlock wires the 2way radio pwr and ground on 5 of our buses. I have seen the rat bodys about a foot long how can he get in there these are 06-07 IC's I thought it was someone messing with us but I have seen the rat briefly as he chased me and I ran away .
I don't think I ever saw an International 3800 that didn't have signs of a mouse in that plastic cover over the electrical on the firewall beside the master cylinder. Never chewed any wires that caused problems, just some insulation missing from wires. But several T444E had nests in the valley and a couple chewed wiring right through.
