I found out where the sparks were coming from. I took the belt off and checked the tensioner, water pump and alternator pulleys. Waterpump and tensior spun like they should. The alternator would spin over 1/2 of the way and then hit something and slow down...it would even come to a stop sometimes. Appears as though the shaft is bent, or a bearing has gone bad letting it bind at a specific point during rotation. It must have been getting awful hot near the end of the run causing material to spit all over the engine compartment. Funny thing, it was still putting out voltage! Wonder how much power that thing was robbing...

I think I might scrap my whole alternator setup and go with a Katech tensioner and a Kwik Performance alternator bracket. I will obviously need a new alternator too. However, looks like the season is over up here in Washington, so I won't have new times until next spring.
