I recently installed from TNT Amusements Frank's lithium coin battery boards in both my Getaway and my TZ. I've noticed on my TZ that the time will not be kept properly when the machine is off, in that when you turn on the machine the time and date will be as of when the machine was turned off. With the Getaway the time is kept accurately. All other settings on the TZ are properly kept. I do not receive the "Time and Date Not Set" error when I turn it on.
When I reset the time and date to be correct and leave the machine on after a few minutes the clock moves to the correct time and keeps the correct time while the machine is on.
So with the TZ is this somehow an issue with the clock on the playfield and its interaction with the clock in the logic board or is this strictly something wonky with the logic board? My TZ clock board is original but long ago modified for LEDs. The machine itself has been in storage for many years but I am bringing her back to life. Everything else on the machine works fine other than I need to replace a dead Geneva switch.
I guess I can swap boards with the Getaway to see if the issue persists but thought I would ask the experts here first if it is somehow related to the playfield clock.
Thanks.
