From 7 to 1 the resistance increases and these wire are primary wires.First, you have to use your DMM to measure all possible combinations of coil resistances, to skull out which are the primary coil leads, and which are your secondaries.
Secondly, where are you, what is your level of expertise, and what is the voltage you will be feeding the primary with ??
I probably have a second-to-none collection of salvaged transformers, and have a system given me by another technician on board for rating coils, which can likely be found in the textbooks.
Clarify what you have and what you intend to do with it, and we'll go from there.
Good question R!f@@ didn't even consider that........ see below......
Yes are these are the primary terminal for AC input. on secondary side they are more terminal i have attach the pictures.Are those all the terminals ?
Any more on the other side?
If i do not do it, how i can learn and became expert.That thing is like child's play mate.
It's just a center tap transformer. The Secondary has Thicker wire coming out. Primary has much thinner wires
All u gotta do is leave all the loops alone and give AC to the both ends of the Primary (which has thin wires).
The loops are to parallel the primary for a 110VAC operation if needed. And this should be done by cutting the loop and wire them accordingly. Which is way beyond you buddy, so it's best not to touch them.
I believe u get 220VAC mains.
Just leave all the loops taped to the transformer.
Connect mains to the ends of the thinner wires (Primary) ... leave all the the loops as it is.
The secondary has thicker wire windings. Measure ur Secondary across the thicker wire ends
i know that. but if i site do not do nothing then how i became an expert.Expert does not become overnight.
