Hi all: I am working on the Central control computer 6-08870-4. too late i replaced the battery. I need a schematic and parts list. I can clearly see that resitors R173,174 were broken. the other resistors in that row 175,176 need replacing too. Looking at the corrosion(green fur) i am also looking to replace q122 and cr116. I can read the values on the resistors, 10,000 for 173,174. 47,000 175. 4,000 176. but don't know what the other parts are rated at. Any help would be great. Mark

Hello Mark,
Q122 is a MPS A56 PNP transistor
CR116 is a small rated silicon diode (use a IN4004 or ssimilar) this is a diode in the 10c coin switch line.
