GOT electric shocked by the BFL Jalapeno or his AC adapter?

A: in country with 3pins 220/240v the middle pin is gound, so the 2pin's doesnt have it.
    so, you either use all 3pins or just all 2pins.

So are you saying if I just buy a 3 pin plug, this will solve the issue...sorry, I have very little electrical experience! Thanks in advance.

No. The problem isn't the plug, I think it's that the power supply can't blow the breaker by itself when it shorts. So instead it runs the power through the jalapeno to the PC which *then* blows the breaker. But by that time, proverbially all hell has broken loose.

I have a jally coming in from the UK which will allow me to test this, paid for and being shipped. I'll post the results on my other thread and update people here as well. Should have an answer within 2 weeks.

In the meantime? I agree that one should cut the cord and wire it into an ATX type power supply, 12 volt rail, yellow and black wires, jumper the green wire to ground to get the power supply to come on. I believe this strongly enough that I did this on my turbo-jally yesterday even though the power supply was working and I'm in the US.

Note: This is my personal opinion, but I would NOT EVEN THINK ABOUT BYPASSING THE GROUND ON THE PC. EVER! That ground is keeping me from getting shocked, and keeping me alive, so I would *NEVER* try to bypass it, no matter WHAT.

Thanks for the update...I look forward to hearing how to you get on with your Jally.

[lightfoot]

No problem. Meantime really look into a better power supply, esp if in 240 volt zones. They're more expensive/different design for a reason.

And for $50 bucks I have a Corsair 500 watt unit coming for my new units, that's not a bad deal.

Based on this post over at BFL I am virtually *positive* this is a ground fault. See:

Note also that an isolator prevents the trip, I think it would save the jally.

Both my Jalapenos blew their power supplies, fortunately they are using 120V and did not damage the actual rigs.

So I replaced them with 12V versions I bought on Ebay and also emailed BFL for replacements which took them 5 days to acknowledge and still haven't seen them.

As a precaution I have replaced all power supplies on everything BFL that I have.

Also my hardware is all plugged into GFI outlets so that bad boy trips with the slightest issue, I'd recommend the same for all.

Would you mind telling us which power supply you bought?

Thanks in advance.

Had same issue with my jala from last batch. They killed my motherboard and died (USB-chip). I hope someone from BFL will....too

Just as a side note, I had a jally PS blow up like this. Fortunately I have isolated power, so no damage to anything.

Yes, they are not good supplies. Everything here is running off a pair of corsairs now.
