Alternator has been replaced as well as battery and all fuses are good to go.

Cryptic messages won't get you the help you need. We need a little more information. Year, make, model, exact problem... things like that.

Eld won't be cheap--will likely require replacing the under hood fuse box ($250).

Where did you get $250. The stealership wants to charge me $466 and change.

With the lack of information you provided, you were lucky I could make any sense of your question. Since I didn't know what kind of car you had, I was thinking a Honda Civic.
