Alternator Smoking?

[gmachinz]

I had a similar problem about a year ago. I made an adjustable heim-end bracket so I could mount a 140-amp 6" case alternator and I did not have the belt tight enough. I ran the shortest v-belt possible to avoid jumping pulleys when I would step into it but I didn't realize how much tighter the tension needs to be between pulleys anytime you significantly decrease the distance between pulleys. Anyway, I starting to notice a faint burning smell but could never find out what it was. Finally after a week or so, my ignition suddenly started acting up and my volt gauge dropped to 0-I broke the damn alternator belt. So, I put another one on and after only 10 minuted idling, the belt began to smoke right on the alternator pulley! The belt tension was okay I had thought but it was sliding around the pulley more than it was grabbing it and turning it. I He-Man'ed the belt tight with only slight tension and I haven't had the problem since. -Jabin
