I finally have bought my first Pin, a F-14 Tomcat. Have had it for a couple months now but noticing some inconsistencies. When I turn it on, sometimes I just get the dreaded constant beep, sometimes I have no sound until I drain the first ball and the second is served up, and I can’t get the game to hold any default high scores when I adjust settings. More importantly I started to get a U25 FAILURE message. I did a lot of reading and switched out the batteries and the error message has seemed to resolve, but I will still get my beep from time to time and default high scores won’t come up when I adjust them.
The owner before me did remove the battery pack off the board and add a remote battery pack...BUT it is only a 2 AA battery pack, should it not be a 3 AA battery pack? It originally had 3 AA’s on the board so I’m hoping getting the proper volts to the board will rectify some of my problems. I just don’t want to add an extra battery and screw up my board without some reassurances, again I’m new to this.
Any advice would be greatly appreciated! PS. I’m not skilled enough to add a NVRAM chip or a Button Cell. I’m just going to move the battery pack into the lower box away from all electrical boards for now. Thanks.
