I get a lot of JVS questions so I hope this helps some people!
Oh yeah that’s like 99% probably your issue. Boards do not like fluctuating power. Especially on the 5V rail. Even a few points off 4.99 / 5.03 can cause stability issues.I have a Sanwa JVS power supply that I got for my Model 3, but it seems to have an issue. I'm entirely sure what the problem is, but it seems like it could be due to the voltage adjustment pot breaking, which causes the voltage to change randomly. I'm not sure exactly how this could be fixed, except I guess just replacing the broken adjustment pot thing. That said, it's possible the problem is actually with my Model 3 rather than the PSU - but given its behavior, the PSU seems like the more likely culprit. By the way, I built an adapter to connect this power supply to my Model 3.
I’d get a new supply
It'd be better if I could get this one repaired; it wasn't cheap. Like I said, I think the adjustment pot just needs to be replaced, which I think should be possible. It'd probably be possible to replace it with something that just has a fixed value, since I don't need to be able to adjust it anyway.
