tensioner

Hello. If you want the short version, I'll put my questions at the bottom in bold. I have a 2001 Ford F-250 with the 7.3 diesel. I am new. I know next to nothing about how to fix vehicles, but I figure me and youtube can do anything,especially when I have too :) I did replace my alternator...

I have been having a time figuring this one out. My belt keeps fraying and coming apart; about 2 or 3 ribs on the front side of the belt. Any Ideas? Some background on what I have done so far: I bough the truck about 2 months ago and had noticed that the belt had some of the ribs ripped off...

the last few weeks ive been getting an intermittent battery light.. itll go on and off randomly for short spurts but the last day or two its been on constantly. i stopped and had a battery load test, which passed and an alt test. it read 11.4v. is there any way i can check if its a tensioner...

To remove the tension off the belt I have read you pull up and out on the bottom of the belt on the passengers side. Is this accurate? Thx
