WANG HOUSE Model:WH-2301S 230watt 12V transformer

My girlfriends Possini light has two transformers in it but I will just talk about one because their both hooked up identically, one to each side of the lights and only one is bad.
Both transformers have a black and white wire on one end that connects to the house wires.This I understand.
On the opposite end of the transformer of my bad transformer there are two red wires. One connects to the black wire and one connects to the white wire of the lights themselves. Here is my problem: The transformer, same model number, that I ordered has two red wires and two white wires on the one end instead of just two red wires like my bad transformer. What are the two extra white wires for? Thanks for any help.

Can we assume there is no wiring schematic on the transformer? Maybe your best bet would be to try and contact there tech support,or if there is a schematic enclose a pic so we can look at it.

Yes, there is no schematic.

Tech support is best but with the working transformer and a multimeter you should be able to figure it out.

Wang House WH-2301S

I was able to track down instructions for the conversion of the back to the original one as follows:
The new version of the WH-2301S now comes with two sets of output wires (2 115W circuits) for a total of 230W. If you only want two output wires instead of four, you will need to combine the wires. This is done by combining the Red to Red and the White to White. The unit is shipped with these wires taped together with electrical tape.
So this new unit can either be used for two separate circuits at 115W each or can be paralleled together for a single 230W circuit which is what the original (older) unit was rated for.

It's a 12V transformer...

Note that, since it's a transformer, 120V goes in and 12V comes out. The black and white go to the 120V house current, the red/white leads are 12V output. They are designed to power two different (red/red and white/white) 12V circuits. That diagram makes no sense. 120V on one side and 120W on the other? Or 230W?
