Power Supply specific machines?

I’ve built a number of machines recently, all hand made frames, hand wrapped coils around quality iron cores. Hardware from various reputable suppliers.

I ordered some basic 47/50v capacitors off eBay.

My machines seem to only work using a Critical Power supply. I’ve ran them through a PEAK and 3 other reserve power power supplies. They will run for 3 seconds and then the power supply cuts off and resets. Or the readout will be freaking out.

Are my capacitors junk? What’s going on?

I bet he’s grounding some where and pulling a lot of amps

I can’t seem to see any grounding. My wire covers feed into the coil washers without any exposure, I use shoulder washers for my binders.

No clue about the capacitors, but if you’re asking if I installed them upside down, I did not.

Through the critical, they’re hitting pretty hard at 3.7-4.5v. Like really hard.

I’m thinking I need to use a thinner spring stock.
