I just ran into something that I haven’t seen yet, any help would be appreciated.
Mac SE FDHD, logic board had removable battery type. Not the soldered battery. Running 6.0.8 with a Blue SCSI hard drive.
I replaced the battery, no corrosion visible. Cleaned machine and rebooted. Everything normal, except the clock/date will not update. I can change time/date but the seconds do move on the clock, they stay at 00. I could come back three days later and the clock/date will be exactly the same as what I set. Also, all the other settings I may have changed will not fall out (mouse movement speed, etc) they remain to what I set. After Dark will not activate, I assume since the clock isn’t being recognized.
I have tested the voltage with machine off and also on (under load). I have good voltage both at the battery and also the positive trace that runs down to the chip.
I’ve never encountered this before, any help would be appreciated.

Sounds like a bad RTC chip or crystal.

Thanks, I was unfamiliar with the RTC chip, I’ll check it when I return home next week.
The little reading that I’ve done about the RTC is that is was a custom part for Apple and there aren’t any replacement parts available, unless a person can pull one off another board. Does that information sounds correct?
I appreciate the hell and will update this once I can take a look at it.
