Murf,

As long as you can determine the primary winding, colored wire won't matter. Connect primary to source, and measure voltages on secondary leads.

Filament windings will have very low resistance across it. The secondary will have three leads. The other "should" be the primary. The primary will have higher resistance across it, than the filament windings.

Measure resistance across each winding in your transformer. Based on what you're saying, it sounds like all of the secondary windings are open. That's not impossible - but it's not likely.
