    Hi, I have a Dirty Harry pinball machine and I havent used it in a while so I changed all the 555 bulbs that were out and made sure everything worked. It does! Problem is everytime I shut it off it reverts back to "Factory Settings Restored" and Bookkeeping totals cleared....My question is, is there a battery backup? It never did this before so I have to assume there was a battery and now it has died and I would really love to replace it. BTW I also have non pinball games i.e pac man upright, ms pac man (added board) and Asteroids I guess I would like to join your forum but its ok if you say no too...If you could just please answer my question I would be very appreciative. Thank you.

    There should be batteries in the backbox, lower left corner. Similar to this image. Get 'em out fast if they are bad to prevent battery corrosion damage to the PCB!

    ....And buy this, install it and put in new batteries ASAP! You need new batteries to hold memory, which includes all settings and high scores, and not show "factory settings restored" every time you turn it on.

    Thank you very much, I forgot about the back panel, had to shuffle around for the key....found it and it works like a charm. Love multiball...
