Sounds like the bridge is sorted but here is a pic of mine to double, triple check.

Can you test the connector with the blue wires to see what reading you get.
Set meter to volts AC, doesn't matter which probe goes on which side.

What reading do you get?

Was in bed, but had to duck out and check this.

That connector is only registering 0.03. It goes up to that, drops and goes back up to 0.03 repeatedly....
