blew 2 60 amp fuses

On my way home from fishing today I noticed my ammeter was way on discharge. When I checked my power distribution box under the hood, I had 2 blown 60 amp fuses. I replaced them and it blew the new ones. The fuses are labeled "alt. pwr. 1" & "alt. pwr. 2". This sucks because I had just decided to keep the Jeep another year or more. I replaced the engine control module 1 year ago and the alternator about 1 1/2 years ago. I had a problem with the Jeep "eating" batteries about every 5 months. Sams Club replaced the battery about 4 times. Then I had to replace the starter about 6 months ago and I also gave Sams the difference and put an Optima battery in it. Knock on wood, the battery has been holding up. That is, until today. I've got it on the charger now. I was just guessing that maybe the old starter was screwing up the batteries.
All this was so you would have a little history. Oh yeah, the Jeep is a 1994 Grand Cherokee Limited with the 5.2. Also, my ammeter is usually way over to the right, but was charging at 14 to 14.2 until today. When I replaced the 2 60 amp fuses it was charging at about 13.8 when I revved the motor, then it blew the new fuses. Thanks, any help would be appreciated.

take it to a parts store .... most check charging systems free... if you think it's the starter then you will have to take it off to test it
