Why is my custom microwave transformer producing inconsistent voltage?

[RED119]

So I was attempting to modify a microwave transformer by wrapping my own secondary coil. The first coil was standard from the microwave, around 16 gauge wire, 100 turns, so I was wrapping my coil with around a 16 gauge wire, I put it together, put a weight on the transformer to keep it together and tested it with my voltmeter and it read around 176 VAC... then I kept winding and tried again but only got .123 VAC, I found this odd so I checked the primary coil, it was getting 120 VAC, it was making the buzzing that transformers do (its 60Hz by the way), when I measured the primary coil it got around 180 VAC, the primary coil was getting hot while the secondary coil I wrapped was cold... I honestly have no idea what is going on or what I did but this is odd stuff... or maybe I am just naive. Here are some pictures to help with analysis:

*primary coil is not measuring 180VAC, it around .320VAC (essentially 0)

Shorted turn somewhere?

Shorted turn somewhere?

I don't think so since I re-wrapped the coil with new wire after it happened the first time, but I still think its worth checking, is there an easy way to check if a turn shorted? and should I check both coils?

the secondary coil is putting out .142 then going up to .180 then back down to around .142 and back up again

enamel coated wire... forgot to sand off the enamel of the new end... my bad
