Is the 7805 getting hot? If so you probably have a short at the output and that is bringing your voltage down

I agree. When you put it in backwards the first time, you destroyed the device. Even if you put it in right this time, it will still fail. You will probably need a new regulator. Be mindful of the orientation of the device.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
