Ok still trying to work out this transformer not sure how to hook it up to find out what output would be the thing heats up supper quick using a 12v car battery no matter what wires I hook it up to also I hooked up meter to check ohms trying to work out whats primary and whats secondary ohms is pretty much the same across the board


Was just wondering what the uses of this would be if nothing I can use it for I think I will pull it apart to see if it is ferite core or not if it is ferite what can I do with it? in the means of power saving device?

Hi TWS

First thing to do is mate all the wire with a ohm meter and tie them together. the largest wire (biggest gauge) is your primary leads
and every thing else are secondary which you have to decide what you can or want to run from the primary. Joule thief can be run from just one set off the secondary and then you can run other things from the other secondary pairs. The resistance will show you each pair set. and you can go from there as to what will save you energy.

Ok done that thats why they have been taped in their pairs well one is not a pair though it actually has 3 wires 2 blues and a white the ohms meter shows 17.8 on all 3 wires as did the 2 orange wires and one set of the blue and red wires the other set of blue and red wires ohms was 16.4 and the primary I am guessing is the black and red pair heaver gauge wire off by itself it reads 4.6 ohms but dont take those figures to the bank as I think my meter is screwed up but it doesnt read anything on the non paired wires so I will go with it just to pair my wires

One step at a time.
Red equal in ohms?
Blue equals?
Orange equals?
Basically pairs, equal.

Attempt to format like above.
The black and possible the white may conform to other pairs.
List that separately, and to which.

Doesn't matter how well the ohm meter is works, as long as it is.

Chances are this is an iron core like RonO said.
Pretty big for what I've seen for ferrite, but who knows..
I just don't wish to see you tear it down before we get an idea of what it is.
Really wish my sites came up with it..

May end up being too big for needs right now.
Who knows what your needs are coming up?
I'm in search of a decent 'step down' transformer for my cousin.
What you have, may be what I'm searching for.
Just sayin'.. You never know what you have may serve a future purpose.

Then again, I'm an electronics' hoarder..

I would hope for a toroid that's ferrite that's a big one if it is. LOL

Ok here I tried to write it down to make sense but it never did in any way I wrote it would get confused with the 2 sets of red and blue and the set of 3 of 2 blue and white
so I took pics of going through the ohms for you to see maybe better than writing it

1st up
red and black heavy wire


2nd up
Red and Blue thinner wire


3rd up
sedcond set of red blue thinner wire same gauge as first set red and blue


4th up
2 blue and a white all three ohms togetherno matter what configuration I hook them to the white does no ohms with any other wire and the black does not ohms with any other wire either






Last but not least
Orange paired with orange

We'll await Doug to explain why the mix of colors are ohm'ing out. I believe I know, but he's much better versed in this.

The Black that doesn't ohm out to anything, I'm betting is the ground.
Again, we'll await Doug to confirm.

Next step will be to determine the wire gauge size.
Knowing the ohm's and the gauge, you can approximate the length.

If you're going to salvage items, a decent wire gauge tool will be very useful.

Hi TWS
As ODR said the black is chasse ground. What did this come out of?? The number od pairs means it ran a number of different systems and with the ground wire there that means Ron O is probably correct with the iron base for you can't use that on ferrite. So with that said use the wire for something. After the rap covering is off it will probably be magnet wire and not covered wire you see now.

yeah the black wire does ohm to the red wire which heavier gauge wire same gauge as black

The wire its self has gauge written on it but I dont think it is correct as the larger gauge wire has a larger number for gauge the the smaller thinner wires

as for what this came out of it was a all in one entertainment center it had radio DVD surround sound stereo and amplifier all in it
there was a ton of stuff inside it and it was extremely heavy which I always wondered why now I know why this transformer is heavy it weighs close to 20lbs

can I not gauge the wire using my calipers?

so can this transformer be used to step up the volts or can it just step down volts?
I am looking for something to increase volts and be able to convert to AC from DC

you can make dc from ac with a FWBR or 4 diodes. you can increase voltage by running pair of orange wires with ac and it will depend on raps of wire around the transformer it is just amps will also go down with the voltage going up.

I was wanting DC to AC not AC to DC
So basically increase voltage will decrease amps and amps is what we all are after.
while we are on the subject of volts and amperes I have a question is my understanding which is limited correct when I say the gauge of wire determines how much amperes versus volts like a thinner wire would produce more volts but less amperes and a thicker wire will produce more amperes but less volts?

To the other question: Yes a good set of calipers will work well.

thanks ODR I have several calipers I use with my welding projects and when I pick up a machinist job here and there

Hi TheWeldShop

I have not been able to devote as much time to replying to some of your questions but if you read the following short manual it should answer a lot of your questions.

google the following :- internet archive b.b.babani
this should show a book ( that you can download freely ) "Coil Design and Construction Manual"

This is an old book ( no mention of toroidal transformers ) but the principles and calculation ( number of turns , turns ratio and current handling capacity vs wire size ) for transformer construction are still valid for toroidal transformers

Hi. i don't know if the transformer you have will be suitable for this, you will have to ask some of the more electrical savy members here for calculations but i thought this was a pretty neat use for a torriodal transformer..
