This spring I resurrected my little chief that had been sitting in storage for over 20 years,it took a lot of tinkering and cleaning but I finally got it working,for the most part, but yesterday it started acting up,it wouldn't give me my accrued bonus points,I could hear something down in the cabinet clicking so I opened the play field and took some compressed air and blew out the points,with a vacuum running,but when I shut the play field and turned on the power and pushed the button to start the play I got nothing! It is set up so you don't have to feed it coins but I tried that anyway,I also tried to give it games up on the back board,but nothing seemed to work!
Any ideas?

After posting I went back out and kept looking,I remembered there were some bare wires up on the game tally wheel,I think from when they set the machine up for free play,sure enough one of those had vibrated down onto a metal bracket,none of the connections had been soldered so I pulled out the soldering pencil and soldered all the connections then taped them.
So that problem has been fixed,I'm still occasionally having the bonus point problem and the center kick out hole doesn't tally,that is a minor problem that doesn't detract too much from the game.
When I had the glass off I wiped the play field with a finger and came up with a fine layer of dust,something I'm going to fight out here.

Hi Peruman, The kick out works but it doesn't count your balls,none of the lights under the kick out hole light up! Thanks

Thanks,I'll get under there tomorrow and see what I can find. There area I live in has really serious blow sand problem,everything get coated with a super fine film every time the wind blows,which is most of the time,hopefully a good vacuum and some canned air will clean it out!.
