[urq] fried starter?

[Gary Brown]

Guys-
 
 After tooling around on Saturday for a spell, heavy on the boost, I let the car cool down by idling a few minutes. When I went to start it up Sunday morning, it would hardly crank over. I thought maybe I left on the dome light, so I hooked up my battery charger. After 15 min or so, I tried it. Same thing, very slow cranking, voltage gauge dropped all the way to zero and the starter is making funny sounds. I just had it rebuilt last August, and up until now it spun nice and fast and quiet.
 Is it possible I fried it??
