Can you wire a transformer in parallel?
Your two are more than likely wired in parallel due to the one transformer being 16 Volts and your multimeter readings being 12 to 20 volts. You'd be better off taking your reading at each transformer after isolating each one to get more accuracy as 12 to 20 V is a big difference. This would also insure each transformer is working. Then you could better determine series or parallel.
