Once a 3000D get's damage from the battery, she can be real work to fix.
The 3k has 3 layers that you need to be concerned about, best bet is to:
1. Review the schematic and see if you can jumper around damage.
2. Try a Indivision ECS and see if you can work around it that way.
Your dealing with the the acid damage, try to neutralize the motherboard if you haven't.
Sometimes you can find a broken trace or read the schematic and test around it to get it sorted out.
Shame, for some crazy reason the 3k is the most neglected big box Amigas, and also the most desirable.
Most of the 3k's I come across have battery damage and have issues. Shame really...
Good Luck!
As a last resort you can send it to the few souls out there that repair Amiga's...
