Long Wei 30v-10a PS problems

Mine has been working great for a long time now. A few days ago, we had an operator error. My youngest knocked the bare wires out of the PS and then I suspect tried to reattach both to the same polarity post. At 11, she hasn't grasped the whole +/- thing yet. We shouldn't have had bare wires either, but were doing some experimenting light arrangements for his fish tank.

They said it sparked some and the cooling fan sped up. At the present time, it only starts the fan for a spin and the LED display lights, but you cannot change the voltage from 0. I opened it up, I didn't see any internal fuse. It's probably tanked, but it's such a shame. I wonder if I should have had that buss bar still attached to the ground post?

I apologise if this is insulting, but have you turned it off, unplugged it, and waited 10 minutes? The circuit breakers the Chinese typically use are tiny little buggers, and resetting can take up to 20 minutes. You could easily have mistaken one of them for something else.

It was unplugged for 24 hours or so, but I'll try that. It's unplugged at the moment, so I'll try again tomorrow night. Thanks for the tip.

I repeated those steps several times and all I've got to say is, "damn it Jim, she's dead"

Go for it, dude. Sounds like that's the way.
