Have a 2002 1.3 L Jimny here in Panama. It's been trouble free until recently. I just replaced the 4th belt in as many months. Everything seems to be aligned perfectly, proper tension, etc. I will hear an unusual noise and then the alternator light comes on. On one occasion the belt actually burned so bad the engine compartment was black with soot. The local mechanics are mystified. Any experiences with this problem? Any suggestions? Help!
