Hi Zuke and All. Here is a photo of the SPP circuit board. I have white circled around the two female plugs. You will note that just above the COND Plug and also to the left of it is a spot for the LED Plug and the Noise Reduction Plug. I have drawn a little white circle with a tiny line to denote these. You will also note the same above where I have outlined the female Pulse Plug. Above that plug reads Pulse Delay To the left of this is my little circle which reads Pulse Width where I assume another plug would be. Its interesting how they have left the COND and PULSE DELAY plugs in place but not the LED... Noise reduction Or PULSE WIDTH Plugs. To the right hand side of the board you will see two connection points...one long and one short with bare brass contacts. I have circled these. Have no idea what they may be. Looks like a way to connect another board in future machines maybe??? Anyway my question to you is.....It looks like a switch could simply be plugged into the Cond. Plug, so would it be worth a try to see what happens.??? Surely it's not going to blow up, is it.??? Tis just a switch. What I know about electronics you could fit on the head of a pin. So I'm no expert, but looking at the rest of the board, it looks very straight forward... Other plugs from the other controls simply plug in to their labelled plugs. What we are obviously not going to get is the three LEDs cause the plug for these is clearly missing. Would need to know which way the three wires would need to go in the switch though. The board number by the way is........505-0255D.
