6.0 Electrical System

So here is the situation been working on it for 2 days now, and kind of need it by Tuesday at the latest.

So my truck started intermittently showing the battery light. At that point metered everything, batteries at 14.2 and alternator putting out 14.6. Then I went to Sears for them to load test the batteries and alternator again. They say they cant find anything else. On my way back from Sears, the battery light is steady on now. Get home, metered it again. 11 at the alternator and 11 at the batteries. Replace alternator, check again and same issue 11 all around. So next day, 12 at the batteries and alternator (truck off) start it, now shows 11. Pull alternator and bring both old and new one to autozone and test. Both putting out 11. They mention about blowing a relay in them. That night I also put a charger on the batteries to charged them, blew the charger. Now I am hearing about the fuseable link, but I dont know where to check this and how to check it. It seems like there maybe a short in the system or what have you.

Any help would be awesome!

If you are getting the same voltage at alt. and batt. with truck off, you do not have a blown fuseable link. With the truck on, but not running you should have voltage at the small wiring harness on the alt. If not, you don't have a signal to tell the alt. to charge the truck.

Thanks for the response. I didn't think it was a fusible link because of that reason, but I was just so lost. It ended up being I bought a bad alternator and was able to return it and get one somewhere else. 200 bucks and running good! Now I don't think the charger blew, but some how it blew the outlet in my timer (the one I use for the block heater). But I returned it anyway. So that's that!
