I fried my power supply turning on my machine for the first time!

[mazzaneo]

Hi guys and happy holidays,

So I just made my cabinet and turned it on for the first time. Upon flicking the switch a I received a loud white noise followed by the smell of burning, not a good start!

The power supply connected to the solenoids is no longer functioning.

I am using Zebs easy install kit and thought I had followed all instructions closely however… on closer inspection I realise that I had connected a few solenoids negative cables to the wrong stud (see pic)

Is this a serious error or should I begin by looking elsewhere, and if so, any tips?

I’m writing here because it is holiday season and I don’t expect Zeb to be available to answer until after the new year.

 

Thanks in advance all.

Electricity is not my strong side. My kit is still down. First of all, are you sure that the PSU is broken and not only a fuse blown ? I’m guessing now, but, I would not be surprised if you have blown one or more Mosfet’s on the way too. I should probably do this myself so, disconnect everything, take out the whole kit as it is easier to work with outside the confinement of the pin. Make sure that all connections are connected correctly and then start to follow the debug guide for the kit. It is in the forums of his site. You will have to own or borrow a multimeter from someone or wait until you get help from Zeb I guess. Good luck and be careful.

Thx Thalamus,

 

You were supposed to say ‘A minor fix, no problem’  lol

Something had to give. You did in a very effective way manage to loop the 12V into a short. I understand the frustration, especially since you didn’t even get to try it out. I’m sure it is fixable, but, if you don’t solder, then it might be that you have to return a board for repair.

So you believe that the fact I used the opposite stud for a negative connection on one or more solenoids could indeed be the reason for the short?

I’m quite sure it is yes. But, not 100% sure. First and foremost, you have to figure out if the PSU is gone or if has a fuse. It is of course needed, no matter how you look at it. If you get that up and running and are connecting everything correctly, you should be able to see what else doesn’t work via Ledwiz tester or what it’s called again. Be aware though, don’t test the ports for any long period of time, that might fry even more. Mosfet might be blown if you don’t get power to the starter, there should be a tip on how to test only the car starter in the guide. If you find it being broken, then I would disconnect it (only the one wire – the other one is needed for the loop, stater to starter), but, make sure that the loose wiring is very well isolated so they don’t touch anything else inside your cab. And – remember, I’m NO expert. So, please be careful.

Well I’ve located the initial problem.

Power supply was set to 110v instead of European 220v.

I’d have to imagine it’s fried. Hope it hasn’t affected other boards.

Ouch. It might have. But, Zeb is also making quality stuff, so my hope and believe is that only some fuses blew. Come to think of it, I might be wrong on the car starter, it might very well be that if you hadn’t forgotten to change the settings on the PSU, you would be ok, just only getting any reaction. I expect this isn’t the first time this has happened, so, my recommendation is that you contact him via his board/email and wait for a reply. Of course, you now know that at least the PSU is dead, so you could always get a replacement yourself, connecting everything the same way as it was. If you are lucky, only the PSU died and you are back in business.
