I am in a bit of a pickle, very frustrated as to why my relay no longer works
As background, I built two boxes, one with a mechanical relay, the other with SSR. Both worked for several years, then the SSR stoped working. I was suspicious that the female 3.5mm input trigger jack had a bad solder, so I bought a more robust input jack (pictured below). Replacing that did not seem to work or fix the situation.
The strange thing: even with no input leads
connected to the SSR, there appears to be enough "leak" to send 0.2V to 2V to the outlet every second or so. This is hard to measure with the multi-meter, but if I connect an iPhone/charger to the trigger outlet, it will cycle like it wants to charge, every 1-2 seconds.
I have replaced the SSR, the outlet, and made sure I have good connections and no shorts. Same behavior, doesn't work.
Any ideas, based on my pic? I've got tip to + and R/S to - on the trigger.
