hey all

im more then sure this has been asked but finding it is a different story

can any one tell me what the out come would be if you were to touch the neg and pos of a 2.5 farad stereo capacitor at the same time with your hand

any info welcome thx in advance

Dunno what voltage would be on the cap you refer to (could be 100vdc plus) but if there is enough pressure there to over-ride the resistance of your skin & deliver the stored current charge (which would be fairly hefty from a 2.5 farad tank), then it is gunna hurt. A lot.

Household RCD's/earth leakage/safety switches are set to trip at 30 milliamps, very quickly (in milliseconds) so that you do not get a sustained boot & killed. No such luxury plowing around in your stereo amplifiers' innards. Like all electric shocks, even if you haven't fried yourself outright, things can get out of wack as a result.....irregular heartbeat possibly leading to heart failure at a later time & so on.

DC also has the nifty trick of causing muscles to contract so that you often cannot let go of the thing that is biting you until it says so (discharged) or some nice person comes along & throws the switch.

Avoid it like the plague, take all precautions. My 2c.

If you are talking a power capacitor running on 12V it's not going to harm you, just like a 12V battery won't zap you.

Just make sure you don't have wet hands if you touch it or metal objects that could short out the terminals to each other or the chassis. Too fast a discharge at 12V is the biggest danger as it could blow up in you face literally if you aren't careful, not that I have actually heard of this happening myself.

If you want to pull this appart I suggest you find out the best way to discharge it first, & then check it with a multimeter to ensure it's safe. If you are not confident seek professional help.

nothing will happen unless your wearing something metal, but these can be used for other nasty items. but wont discuss on here.

beware they can become hot when you first charge them without the resistor, and they can spark

no idea why you asked this ??

probably best if you dont put your tongue on it 9v battery style...

which made me laugh about the time I suckered a friend with a tongue piercing to do just that with 9v battery, funniest thing ever to see a spark fly off there tongue..hahahah I'm a sick bastard but it was funny

hey guys thanks for the replys

the reason for asking is friend has one in his car with exsposed terminals 12v system and would be easy to touch by mistake.

Just wasen't sure if it was going just give him a zap or cause severe damage like blow of a finger

i play with stereo's on a dayly basis (tuning) but never had a need for any cap to be placed in the system

sorry for the lack of info in my first comment

anything metal will spark and possibly cause a fire, cover the terminals somehow

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
