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.

I thought about that but I have tested continuity through the connector while tugging on each wire and each one tests fine. Makes me think it’s less likely that it’s the connector.

Sounds reasonable. I’ve crimped connector pins before so probably will be my next step. Swapping the 2 node boards is also a good suggestion that I might try.

Thanks

Yes this makes a lot of sense; I’ll do this next time it acts up but it might be a while until I can get to it. The pro is actually on loan in my son’s house (I have a JP premium at my house).

And greatly appreciate everyone’s advice.

Yes

That’s great news.
