R34 Alternator Rated Output

[kitto]

Window down half an inch?

Still doesn't effectively demist the window. I'd really like one of those demister kits rally cars and so on use for front windows, but no one seems to do them at a reasonably price..

Rocket industries has alternators up to 200 amps that might suit your quest ?

wont bother commenting any further , I'm australian and not one supplier i know use mm2 crap , its not even labeled that way on the jacket or catalog ffs ?

(beware most mm2 wire jacket isn't heat stable beyond 70c and it gets hotter then that under a bonnet ) but you know that just for readers of this thread , the jacket becomes brittle

Dc and Ac are not the same - ac kills you dead or blows you across the room if your lucky !!

And never use solid core wire on a car !!! For those reading this

Try rb28 diesel engine maybe ? they came in the nissan 4x4

Just buy a cabby fan that plug into cig lighter haha

Overkill for what i need, Rocket industries are pricey.

Thats because your into car audio, they all use AWG. So much trend for following Americans. Standard building wire, either in solid or stranded core as an Australian standard not in the Automotive industry is done in mm2. Why am i using mm2 wire? Because its what i use everyday, i know what each size cable is rated too and i get it for free. Why would i use AWG?

Not entirely true. The very cheap cable becomes brittle and deteriorates quickly. You shouldn't be running wiring in an area of the engine bay where its stupidly hot anyway.

Dc and Ac are not the same - ac kills you dead or blows you across the room if your lucky !!

Ok, umm this is stupid quote of the day, AC and DC have different electrical characteristics yes. If you think for one second that DC won't kill you, you a dead wrong buddy. DC is more dangerous than AC in the fact that DC Causes your muscles to contract and will not let you un-contract. Your muscles overheat very quickly and begin to burn up. You then begin to spasm. DC will give you a friggen boot so painful you won't know what the hell happened.

Ahh but you say i can touch a 12V battery, both terminals no problem. Thats because you need approximately 50V DC or AC to penetrate your high resistive skin. 50 - 100mA of current (AC OR DC) passing directly over your heart is enough to kill you. At around 40mA your heart begins to fibrillate (makes your heart go out of time) causing very bad chest pain. After this, most people's heart fail and they die. This is electrocution.

AC current goes from peak high, back through zero to peak low 50 times a second here in Australia (50Hz), this causes the muscles to contract - un contract and so on. A person is usually able to let go or move away from the source that is giving them the electric shock.

At the end of the day, it doesn't matter if its AC or DC or even what voltage it is. It is the CURRENT that kills you. Although, the higher the voltage, the MUCH easier it is for you to receive an electric shock or die. The higher the voltage, the easier it is for current to pass through you. In voltages that in the high kV area, if your on the ground and you get close to one of the conductors, you dont even need to touch it, the high voltage will jump the gap, travel through you down to earth, killing and vaporising you at the same time.

And you said your an electronics engineer? I would have thought you should know a lot about this...

This is a man in India, that dies from his body coming into contact with the overhead DC conductor. Yes, DC is dangerous and not to be treated lightly.

When i am working around a battery bank that is above 48VDC it worries me more than working around 400VAC three phase.

And never use solid core wire on a car !!! For those reading this

This one is a no brainer....

Maybe viable.

Haha thanks for the copy and paste on dangers of DC you have nfi about my skill level mate its severely dumbed down on a forum for entry level people

Dangers yes any " current" ac or dc , grab a spark plug wire thats DC about 20-50,000 volts and not a nice feeling in the arm

More danger on a car is unfused wires or wrench across the terminals , spark plugs while running , airbags , static electricity and fumes , or a new danger hybrid and electric cars with super high current and voltage , wearing metal watches and rings etc around cars moving parts or power

The solid core comment is because I've seen it done a dozen times before

Best of luck on your quest

FYI I've been zapped on 12 and 24v more times than I can remember. Changing starter motors on hydraulic shovels with 70 odd degree engine bays has got me more than a few times.

Anyway off topic

It wasn't a copy and paste buddy. After all i'm just an electrician that is specialised in the industrial automation field, what would i know about the dangers of AC and DC huh.

Yeah, typical engineer's attitude.

Honestly i'm over arguing with you, you seem set in your ways. Good luck.

Yes, this is most definitely possible, Its possible and has happened from 6V batteries before. It depends on a few factors, sweat on your hands, humidity etc.

The higher the voltage, AC or DC, the easier it is for current to flow through you.
