Can anyone explain what specific purpose do the capacitors and diodes serve in the EM game Centigrade 37? I can not get my Alternating relay to work and I have narrowed the problem down to these components. If I knew how these components related to gameplay it would probably help alot.
I am not a noob but far from an expert with schematics and pin repair. From what I can tell there is a capacitor and two diodes that relate to the alternating relay. The alternating relay is not an interlock relay. It looks like it always has power being applied when it is on. There is more than one switch in the path but basicaly it turns off and on with the match relay activity. If the game ends and the alternating relay is powered on, it stays powered on. It looks like the capacitor (and diodes) is there to drain the power to the Alternating relay and turn it off before it burns up. Am I right or am I totally off here?
There appears to be a capacitor in the circuit that awards a replay for a match and/or a score award replay. The PC boards on the decagon units related to these functions seem to get pitted and actually holes burned through the traces. Is the capacitor on these circuits an attempt to alleviate this issue? Is the fact that this capacitor is 40 years old (and likely failed) the reason these boards get pitted?
Any input is greatly appreciated.
