It could possibly be the fuse for the alternator. Please check it.

If you can get ahold of a voltmeter, i would like to know the voltage reading at the battery with the engine running at fast idle. Do you have one?
That was a fast check!
You mentioned that it worked ok from sunday to tuesday.....when was this reading taken?
I'm thinking that possibly the new alternator is at fault. Can you get another reading?
What year is this monster?
I'll look at Kia's service bulletins and see if this has been reported before.
Unfortunatly there is no mention of this as being a common issue. Its going to have to go into the shop in order to track it down :-( Sorry, but thats really all i can do from here.
Best of luck my friend!
