Amiga 4000 down!

ouch.
Good luck with getting the repair work done. Doing a battery change is one thing. Less pins...

I think the A4000 I just bought has some issues with the RTC. Under investigation...  The Time Prefs won't save. It will keep time while running and resets back to the OS install time and date from a few days ago after a reboot or restart.

The traces look ok with some slight damage from the corrosion. But I can't be certian of what the traces run to and from without a schematic or A4000 mb diagram...

I had a similar situation. The traces didn't look too bad, even with a 20x magnifier. But I measured the resistance of couple of the nearest traces to the battery. The nearest one was broken; a jump wire cured it.

Can't find my magnifying lamp, but i figure that might be the case. I put the original HD back in and it's time/date is stuck March 1st 1978.  My guess is the battery failed and the guy never attended to it, then the corrosion set in affecting the RTC circuit. He, the original owner, claimed it was "recently" taken off line at his production facility and "everything" worked fine.  Just got received the Warp'40 Engine today. Was hoping to have the case closed by tonight...
