I just want to say that the A3000 is the Rolls-Royce of Amigas when it comes to build quality. I actually just did the battery hack on mine last night. One of the screws holding the MB down even had to be drilled out as it was not going to budge!(not disturbed in 15 years will do that I'm sure). After all that abuse, the thing still works like a peach (and keeps the time/date now).
Sorry to hear yours isn't working. I'd also suggest checking to make sure there isn't a short somewhere (count your screws!) and then checking the power output.
