   What is your current unit rated for 60A?   
      
   I replaced the 70A alternator in my truck when a diode opened up.  It   
   was still working, but not enough juice to charge the battery when the   
   lights were on and I run the headlights all the time, lol.  Nothing ever   
   got fried though.   
      
   What is your alternator model number?  What year?  Mine is a 97 T100 and   
   I found they changed the alternator in mid model year (around April,   
   IIRC).  Causes a lot of confusion on what is the right model.  I tried   
   finding a replacement diode bridge.  *That* was the major change and was   
   incompatible between the two versions.  When looking for parts be sure   
   to use the VIN to get the right one.   
      
   I ended up getting a used alternator and it is running ok now...   
   although it is in the shop for a clutch.  They've ordered two so far.   
   The first pressure plate "collapsed" whatever that means and the springs   
   on the second weren't right.  They are giving NAPA some hell over this   
   and are getting an upgraded one to put in my truck.  Hope to have it soon.

   A 70 amp alternator is not a very large capacity one.  I think my old 1999   
   Mercury Cougar has a stock replacement 110 amp alternator.  I burned out the   
   first one using dual subwoofers and an amp that I added.  I took out the   
   subs and replaced the battery too after replacing the alternator.  I live in   
   central Canada where it gets really cold, so I put a charger on the battery   
   two or three time during winter to keep the battery at top charge.  If you   
   are making short trips with your vehicle, your battery does not have enough   
   time to recharge between starts and eventually the charge will keep   
   decreasing which puts a heavy load on your alternator right after starting   
   it.
