looks like the battery has leaked. Any way to clean up?

Try to rub the mobo with an used toothbrush and ISO, plus reseating the around components.

 I've see your board don't have a 68k socket(?!? WTF!). If this is true, you MUST dessolder teh CPU, place a socket and plug a NEW (maybe the old) CPU on it.

Use toothbrush and brush off the corrosion area.  Look at the traces and make sure that they are not corroded through.  Check any chips that maybe had some of the corrosion on the legs and make sure to brush it off too (sometimes leg on an chip can get connected by corrosion and cause the chip to short.  Forget the battery its only used for time and date anyways.  I have repaired A4000 MBs with really bad corrosive damage (3yrs stored after they stopped working).  Use alcohol with q-tips a plenty to make sure it is cleaned to the t.  Good luck

remove the socket and solder the proc directly to the board.

similar example:

It looks to me as if the topmost (thick) battery trace is completely corroded away around the battery terminal area.  I'd reconnect the solder points along that trace with wire and see what happens before anything else.

g'luck!

Thanks for all the help with this one guys but nothing has worked as yet. I think that maybe coldfishes suggestion is now the only hope, bar sourcing another a2000 motherboard.

This weekend is the big jobby.

On a positive side i sourced an unexpanded a1200/40hd. :-D  Now i want to put a spare 30gb laptop hd inside of it. I also have one for my a600 hehe. Problem is i just can't find a local supplier with the correct ide cables for em. :madashell:

Anybody know of the best place to source these. any suggestion appreiated.

cheers

another common problem with 2000's is the god damn fuses. It might be that your amiga is playing dead not because of the battery leak but a blown fuse.

[lord_smeag]

How would i test the fuses?

[orange]

with digital multimeter, of course. the fuse should be 'resistor' with 0 Ohms (a short). if its open then its blown.
