SincevI cannot see any charring I will take Greg's word for it. Inspect it. If does not help, then:
Take a verything off, I mean disconnect everything all the way to the xfmr leads
Size up a load that would take 10.5A @2.5V (this would have to be a power resistor of about 0.23 ohm), connect it RIGHT at the leads well. No alligator clips or thin wires.
Then connect voltmeter at the load and see the voltage. If it drops significantly from 2.5V you have a weak connection inside the xfmr. Inspect and if accessible, resolder. There is no turn short. And there is no such thing as weak winding for this kind of load, they do not weaken, , has to be the connection that is soldered to it. If not accessible, then oh, well...

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
