Quoted from Jenk540i:Ever since I have owned my JP pro I have had intermittent failure of the right ramp and right orbit to register. (Switches 52-54). Occasionally it is just the right ramp but usually it’s all 3.
After testing switches and continuity I know the issue is pins 2-4 of CN12 on node board 8. Because when it occurs I remove that connector and push it back on and it will work for weeks and then the switches will stop registering again. And when those 3 switches fail to register the other switches on the connector still register (pins 5,6,7,and 9). Not sure if the problem is the plug or the board/pins.
I have repaired boards from W/B systems where I have reflowed solder. But I have never messed with a Stern node board and I know if I damage one there are no available replacements now.
It’s not the end of the world to have to reseat that connector every few weeks but it is an annoyance. Reseating the connector works every time.
Hoping someone with more node board experience might have a suggestion. Thanks.

The dead simple way to isolate your problem is to swap node 8 and 9 (changing the dip switches so each knows its new role) and see if the problem moves to the left halfpipe (which is on node 9, CN12, pin 2). If after the swap your problem remains on node 8, it's the wiring or connector itself. If it moves to the node 9 (which was node eight) it's the node board pins, most likely.
