Re: I just accidentaly destroyed my Fortron Blue Storm II

Just for the record, the PSU housing is not only for protection against accidental touching of live wires but also to direct the airflow properly so it goes over the heat sinks and other hot components. Removing the sheet metal changes the airflow pattern and can overheat things.

get an extension cable, cut it in half and put an earth-leakage breaker inline.

Re: I just accidentaly destroyed my Fortron Blue Storm II

Start with checking the fuse and input rectifier, the heatsinks are grounded to rectified ground which may still be on different potential than the earth ground. Otherwise the silicon in FSP PSUs is for many years in fully insulated TO-220F packages so no other silicon should be affected.

The 100uF cap on the auxiliary rail from stand-by supply is gone too. If you want I have D8 caps just for these units as they are still quite common and known to go bad because of bad custom crapacitors so I can supply you.

Thank you for offering to help me, but as I said up there, I gave it to the repair store.

Yes, they are... but the question is, does your house have proper grounding? Because if not, then the case can become live without tripping anything. Modern electric codes in most countries now require a safety ground on each outlet. However, there are still plenty of old houses in many parts of the world that don't have grounded outlets, including here in the US. As a matter of fact, I lived in one like that while in college. The thing is, I had hardwood floors everywhere and the house was sitting a few feet from the ground, so I could touch live wires all day and not get shocked . Just keep away from sinks, pipes, faucets, coaxial cables, and other (possibly) grounded objects.

The fuse in my house burned when this happened, so that would mean the grounding is alright?

I just want to add one thing so you understand how lucky you where.
You lifted the PSU and first contacted ground THEN the live heatsink.

If it would have been the other way around, (live heatsink first) then the current would have gone through your body looking for a ground.
So if your feet where grounded it would go that way.
If your other hand was holding the chassis of the PSU it would have gone through your arms.
Just so you understand how serious this is...

Thanks, I will for sure think about this next few nights before I go to sleep, I was holding the cap with both of my arms.

When I was in the U.S. Army AIT Signal school for FEERC the fist thing the insructors taught us was to always remove rings, watches and dogtags from ourself before repairing electronics and also to keep one hand at all times in your pocket.

And with good reason.

It should be obvious but just in case - there is heart on both these paths. If the voltage induced was AC than you have problem. If it is just DC potential it is not so serious, you would get some electrolysis in your vains and you would drop it. But with AC you get muscle spasm so you cannot let go of the thing you hold.

yea, he needed to add that you have to make sure haliburton didnt install the shower pumps!

PSUs are always grounded like this to save idiots like me, right? If not, then fuck, I will get shivers every time I think about how close I was to being possibly dead that day.

Re: I just accidentaly destroyed my Fortron Blue Storm II

lol - try that with 240v.
you will be on your back, trust me - i know!

You can try it even with a 1000 V. It won't hurt one bit if you are well-isolated from ground. On a dry hardwood floor in a wooden house, you just won't get shocked. Now don't try that on a concrete or ceramic tile floor! (or even brick, for that matter.) Also, wearing good (dry!) shoes helps too .

keke lying on your back with 240v...

electrotherapy massage anyone? full payment upfront for the massage. no refunds if it kills you!

Nowadays breaker rather than fuse, fuses are replaced by breakers here at for at least 50 years.

its for electrical safety in case sheet happens and the live wire somehow breaks loose and touches the metal casing. this will immediately cause a short to ground thru the earth wire blowing the fuse and cutting off the power thereby preventing anyone touching the metal casing from getting zapped.

Re: I just accidentaly destroyed my Fortron Blue Storm II

the fuse is near where the power wires go on the board - show a foto

ok, the fuse is on the corner of the board in a black sleeve.
just desolder it and cut the black sleeve away to read the numbers on it.

Re: I just accidentaly destroyed my Fortron Blue Storm II

@stj & momaka thank you for your help, but I really don't know where the fuse is, I decided I'll take the PSU to the repairshop and explain what happened to the repairmen
this repair, no matter how simple it may be, is too hard for me

@dragos2009 that is a nice find really! thank you, didn't even notice and you found it on the picture

@ChaosLegionnaire Lesson learned, I assure you. I'm never messing around with high voltage components anymore...

Re: I just accidentaly destroyed my Fortron Blue Storm II

well, inexperienced users shouldnt be doing reckless things like running a psu while it is opened up.

u could have ended up dead as a burnt smoking corpse from the short u caused. thank god for the earth wire. thats what saved u from being zapped.

as a former ambulance medic, i actually dont enjoy doing cpr and having to defibrillate people. (sorry u had to hear that from me)

i hope u have learnt your lesson and exercise better electrical safety in future!

Re: I just accidentaly destroyed my Fortron Blue Storm II

you have 3 bad caps the other one is hidden under the output wires

Re: I just accidentaly destroyed my Fortron Blue Storm II

Always replace bad caps and caps of the same brand and series ! Always Always Always if you want your device to work and be more reliable !
