Pole Position
A tech that use to work for an old operator showed me this: He was constantly having to replace the small 1/4 watt resistor on the AR board and having intermitent problems with game.
Best thing I ever did,
Pick up some 16 to 20 ga wire(I like the stranded because it is more flexable) along with a handfull of Female spade connectors that match the ground test points on the PP boards and the AR boards. I crimp and solder the spades out of habit.
From AR to AR to the main P1 to P2 ,tye the grounds together using One test point on each of the boards. Alot of the problems with the PP boards was complements of the edge connectors grounds getting flakey. I also removed the daughter board and go directly into the main boards with the wirring harness.
I have also done this for the +5 volts line. I set the Voltage from the AR board at 5.1 at the Test point of one of the Main boards. I only had black wire at the time so the +5 wire is marked with a piece of red tape on each end.
Did not add extra wire, for the 22 volt or 12 volt lines.
I redid all of the earth grounds, using a screw and a star washer to get a better bite on the metal.
I also mounted a small 12vdc fan that draws air accross the boards from the back to the Front.
This has keeps my Pole Position Alive and (Knock on Wood) free from Problems.
I also installed the AR II board kits from Bob Roberts.
I replaced the Big Blues, capped/rejuved the Monitor. You got to love the picture on the Monitor, especially for it's age. Some Burn but I feel that adds to the game.
This has keeps my Pole Position Alive and (Knock on Wood) free from problems. My Pole Position was the first game I ever bought.
