A3000 repair

[kirk_m]

So after not doing much Amiga related for a while, I found myself in possession of a nice looking Amiga 3000. Unfortunately the battery leaked and did some damage but I caught it before it got as bad as most of the pictures I've found online. Unfortunately it acts essentially dead. I've verified the power rails all look good and gotten as far as observing a roughly 1-second burst of activity on the buses and ROM enables when power is applied or I manually assert the _FAIL signal but then it goes dead. The clocks are still active but the address and data buses are static. I'm not real familiar with the Amiga architecture but my suspicion at this point is that it's starting to load the ROM and then crashing. Are there any common issues that can cause this? I was under the impression that the area around the battery is primarily video circuitry so I haven't yet desoldered any of the ICs in that area to inspect closely for hidden damage but it cleaned up pretty well and I don't see any rotted out traces. Does the Amiga have any sort of built in diagnostic like the POST codes on a PC? The machine was found in a hoarder house that was being cleaned out so I have no knowledge of it's previous status.
