RTC not keeping the correct time or date
« on: July 21, 2012, 10:39:48 AM »
I soldered a CR2032 coin battery holder and a 1N60 diode in my Amiga 2500 motherboard.  Poped in a new battery, and the RTC is not keeping the correct time or date.  I unsoldered R803 and soldered the 1N60 diode in its place.  Polarity on the battery holder and diode are correct.

Anyone know why my RTC is not working?

I am wondering if R803 should be left in the circuit, because electricity takes the path of the least resistance.

Is it losing time, or not saving? I have a few machines setup that way with no problem. My 2000 only lost an hour or so after being powered off a year.

Not saving. I baught the CR2032 coin battery from Radio Shack. I noticed that many people use a 1N914 diode, I wonder if this would be a better diode to use instead of the 1N60.
